feat: suivi de la progression de lecture par livre

- API : nouvelle table book_reading_progress (migration 0016) et module
  reading_progress.rs avec GET/PATCH /books/:id/progress (token read)
- API : GET /books/:id enrichi avec reading_status, reading_current_page,
  reading_last_read_at via LEFT JOIN
- Backoffice : badge de statut (Non lu / En cours · p.N / Lu) sur la page
  de détail et overlay sur les BookCards
- OpenSpec : change reading-progress avec proposal/design/specs/tasks

+## Context
+
+L'API est une application axum single-user protégée par tokens (`admin` / `read`). Les données sont dans PostgreSQL, gérées via sqlx. Les routes existantes sont groupées en `admin_routes` et `read_routes` dans `main.rs`. La table `books` stocke uniquement les métadonnées de contenu (titre, auteur, pages, etc.) sans aucune notion d'état de lecture.
+
+Le `GET /books/:id` utilise déjà un `LEFT JOIN LATERAL` pour les `book_files` — le même pattern s'applique naturellement pour la progression de lecture.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Stocker et exposer l'état de lecture (unread / reading / read) par livre
+- Mémoriser la page courante pour reprendre la lecture
+- Horodater la dernière activité de lecture
+- Enrichir `GET /books/:id` sans breaking change
+- Documenter tous les endpoints dans Swagger via utoipa
+
+**Non-Goals:**
+- Support multi-utilisateur (pas de concept d'utilisateur dans l'app)
+- Historique des sessions de lecture
+- Synchronisation entre clients
+- Progression sur `GET /books` (liste paginée — impact perf non justifié)
+
+## Decisions
+
+### D1 — Table séparée `book_reading_progress` (vs colonnes sur `books`)
+
+`book_reading_progress` avec `book_id` comme PRIMARY KEY (relation 1-to-1).
+
+**Rationale** : sépare les métadonnées de contenu (immuables, issues de l'indexer) des données de lecture (mutables, issues de l'utilisateur). Facilite les requêtes ciblées et isole les permissions futures si multi-user.
+
+**Alternative rejetée** : colonnes directes sur `books` — plus simple mais mélange deux responsabilités différentes dans la même table.
+
+### D2 — Upsert sur PATCH (INSERT ... ON CONFLICT DO UPDATE)
+
+Une seule ligne par livre, créée à la première mise à jour. Pas de `created_at` dans la table.
+
+**Rationale** : évite un GET + INSERT/UPDATE en deux temps. La sémantique "créer si absent" est transparente pour le client.
+
+### D3 — Token `read` autorisé à écrire la progression
+
+Le PATCH est ajouté dans une section de `main.rs` protégée par `require_read` (pas `require_admin`).
+
+**Rationale** : le cas d'usage principal est une app de lecture tournant avec un token read-only. Exiger un token admin serait inutilement contraignant pour une opération purement personnelle.
+
+### D4 — Réponse par défaut si progression inexistante
+
+`GET /books/:id/progress` retourne `{ "status": "unread", "current_page": null, "last_read_at": null }` si aucune ligne n'existe, plutôt qu'un 404.
+
+**Rationale** : simplifie les clients — pas besoin de gérer un 404 comme état "non lu". L'absence de progression EST l'état "unread".
+
+### D5 — `current_page` : valeur positive sans validation contre `page_count`
+
+Accepter toute valeur `> 0` sans vérifier que la page existe dans le livre.
+
+**Rationale** : `page_count` peut être NULL (phase d'analyse pas encore terminée). La validation côté client est plus appropriée.
+
+## Risks / Trade-offs
+
+- **Pas de validation de page** → un client peut enregistrer `current_page = 9999` sur un livre de 10 pages. Risque faible dans un contexte single-user personnel.
+- **Token read en écriture** → légère déviation du principe least-privilege. Acceptable car la progression n'affecte pas les autres données.
+- **LEFT JOIN dans `GET /books/:id`** → requête légèrement plus lourde. Impact négligeable (1 row lookup sur clé primaire).
+
+## Migration Plan
+
+1. Déployer la migration `0016_add_reading_progress.sql` (non-destructive, nouvelle table)
+2. Déployer le binaire API avec les nouveaux endpoints
+3. Rollback : supprimer la table et redéployer l'ancienne version (aucune donnée critique perdue)

+## Why
+
+L'application ne permet pas de suivre la progression de lecture d'un livre. Il est impossible de savoir quels livres ont été lus, lesquels sont en cours, ou de mémoriser la page courante pour reprendre là où on s'est arrêté.
+
+## What Changes
+
+- Nouvelle table PostgreSQL `book_reading_progress` pour stocker l'état de lecture par livre
+- Nouvel endpoint `PATCH /books/:id/progress` pour mettre à jour la progression (accessible avec token `read` ou `admin`)
+- Nouvel endpoint `GET /books/:id/progress` pour consulter la progression d'un livre
+- Enrichissement de `GET /books/:id` avec les champs de progression (`reading_status`, `reading_current_page`, `reading_last_read_at`)
+- Documentation Swagger complète via utoipa pour tous les nouveaux endpoints et schemas

+- `reading-progress`: Suivi de l'état de lecture d'un livre (unread / reading / read), avec mémorisation de la page courante et horodatage de la dernière lecture
+
+### Modified Capabilities
+
+- `book-details`: Le détail d'un livre (`GET /books/:id`) expose désormais les informations de progression de lecture
+
+## Impact
+
+- **DB** : nouvelle migration `0016_add_reading_progress.sql`
+- **API** : nouveau module `apps/api/src/reading_progress.rs` avec 2 handlers axum
+- **API** : `apps/api/src/books.rs` — `BookDetails` enrichi + requête SQL modifiée (LEFT JOIN)
+- **API** : `apps/api/src/main.rs` — ajout des routes dans `read_routes` (GET) et dans une section accessible au token `read` (PATCH)
+- **API** : `apps/api/src/openapi.rs` — enregistrement des nouveaux composants Swagger

+## MODIFIED Requirements
+
+### Requirement: Consulter le détail d'un livre
+Le système SHALL retourner les détails d'un livre via `GET /books/:id`, incluant désormais les informations de progression de lecture : `reading_status` (valeur par défaut `"unread"`), `reading_current_page` (nullable), et `reading_last_read_at` (nullable).
+
+#### Scenario: Livre sans progression enregistrée
+- **WHEN** le client appelle `GET /books/:id` pour un livre sans progression
+- **THEN** le système retourne HTTP 200 avec les champs de progression à leurs valeurs par défaut : `reading_status = "unread"`, `reading_current_page = null`, `reading_last_read_at = null`
+
+#### Scenario: Livre avec progression en cours
+- **WHEN** le client appelle `GET /books/:id` pour un livre dont la progression est `reading`
+- **THEN** le système retourne HTTP 200 avec `reading_status = "reading"`, `reading_current_page = <n>`, `reading_last_read_at = <timestamp>`
+
+#### Scenario: Livre inexistant
+- **WHEN** le client appelle `GET /books/:id` avec un UUID inexistant
+- **THEN** le système retourne HTTP 404

+## ADDED Requirements
+
+### Requirement: Consulter la progression de lecture d'un livre
+Le système SHALL retourner la progression de lecture d'un livre via `GET /books/:id/progress`. Si aucune progression n'a été enregistrée, le système SHALL retourner `{ "status": "unread", "current_page": null, "last_read_at": null }` sans erreur 404.
+
+#### Scenario: Progression inexistante
+- **WHEN** le client appelle `GET /books/:id/progress` pour un livre sans progression enregistrée
+- **THEN** le système retourne HTTP 200 avec `{ "status": "unread", "current_page": null, "last_read_at": null }`
+
+#### Scenario: Progression existante — livre en cours
+- **WHEN** le client appelle `GET /books/:id/progress` pour un livre avec `status = "reading"`
+- **THEN** le système retourne HTTP 200 avec `{ "status": "reading", "current_page": <n>, "last_read_at": <timestamp> }`
+
+#### Scenario: Livre inexistant
+- **WHEN** le client appelle `GET /books/:id/progress` avec un UUID invalide ou inexistant
+- **THEN** le système retourne HTTP 404
+
+### Requirement: Mettre à jour la progression de lecture
+Le système SHALL permettre de mettre à jour la progression de lecture via `PATCH /books/:id/progress`. Cette route SHALL être accessible avec un token `read` ou `admin`.
+
+#### Scenario: Marquer un livre comme lu
+- **WHEN** le client envoie `PATCH /books/:id/progress` avec `{ "status": "read" }`
+- **THEN** le système enregistre `status = "read"`, `current_page = null`, `last_read_at = NOW()` et retourne HTTP 200 avec la progression mise à jour
+
+#### Scenario: Marquer un livre comme en cours avec page courante
+- **WHEN** le client envoie `PATCH /books/:id/progress` avec `{ "status": "reading", "current_page": 42 }`
+- **THEN** le système enregistre `status = "reading"`, `current_page = 42`, `last_read_at = NOW()` et retourne HTTP 200 avec la progression mise à jour
+
+#### Scenario: Réinitialiser la progression
+- **WHEN** le client envoie `PATCH /books/:id/progress` avec `{ "status": "unread" }`
+- **THEN** le système enregistre `status = "unread"`, `current_page = null`, `last_read_at = NOW()` et retourne HTTP 200 avec la progression mise à jour
+
+#### Scenario: current_page manquant pour status reading
+- **WHEN** le client envoie `PATCH /books/:id/progress` avec `{ "status": "reading" }` sans `current_page`
+- **THEN** le système retourne HTTP 422 avec un message d'erreur
+
+#### Scenario: current_page invalide (zéro ou négatif)
+- **WHEN** le client envoie `PATCH /books/:id/progress` avec `{ "status": "reading", "current_page": 0 }`
+- **THEN** le système retourne HTTP 422 avec un message d'erreur
+
+#### Scenario: current_page ignoré pour status non-reading
+- **WHEN** le client envoie `PATCH /books/:id/progress` avec `{ "status": "read", "current_page": 42 }`
+- **THEN** le système enregistre `current_page = null` (la valeur fournie est ignorée)
+
+#### Scenario: Livre inexistant
+- **WHEN** le client envoie `PATCH /books/:id/progress` avec un UUID de livre inexistant
+- **THEN** le système retourne HTTP 404
+
+### Requirement: last_read_at mis à jour à chaque modification
+Le système SHALL mettre à jour `last_read_at` à l'horodatage courant à chaque appel `PATCH /books/:id/progress`, quel que soit le statut.
+
+#### Scenario: last_read_at actualisé sur tout changement
+- **WHEN** le client envoie `PATCH /books/:id/progress` avec n'importe quel statut valide
+- **THEN** `last_read_at` dans la réponse est égal à l'heure de la requête (NOW())

+## 1. Migration DB
+
+- [x] 1.1 Créer `infra/migrations/0016_add_reading_progress.sql` avec la table `book_reading_progress` (book_id PK, status TEXT CHECK, current_page INT nullable, last_read_at TIMESTAMPTZ nullable, updated_at TIMESTAMPTZ)
+- [x] 1.2 Ajouter un index sur `book_reading_progress(status)` pour faciliter les futurs filtres
+
+## 2. Module reading_progress.rs
+
+- [x] 2.1 Créer `apps/api/src/reading_progress.rs` avec les structs `ReadingProgressResponse` et `UpdateReadingProgressRequest` (avec ToSchema pour Swagger)
+- [x] 2.2 Implémenter le handler `get_reading_progress` : vérifier que le livre existe (404 si non), LEFT JOIN sur `book_reading_progress`, retourner la valeur par défaut `unread` si absent
+- [x] 2.3 Implémenter le handler `update_reading_progress` : vérifier que le livre existe (404 si non), valider `current_page > 0` si `status = "reading"` (422 sinon), upsert via `INSERT ... ON CONFLICT DO UPDATE`
+- [x] 2.4 Ajouter les annotations `#[utoipa::path(...)]` sur les deux handlers (tag "reading-progress", params, request body, responses 200/404/422/401, security Bearer)
+
+## 3. Enrichissement GET /books/:id
+
+- [x] 3.1 Dans `apps/api/src/books.rs`, ajouter les champs `reading_status`, `reading_current_page`, `reading_last_read_at` à la struct `BookDetails` (avec ToSchema)
+- [x] 3.2 Modifier la requête SQL de `get_book` pour inclure un `LEFT JOIN book_reading_progress brp ON brp.book_id = b.id` et mapper les champs (valeur par défaut `"unread"` via COALESCE)
+
+## 4. Routes dans main.rs
+
+- [x] 4.1 Déclarer le module `reading_progress` dans `apps/api/src/main.rs`
+- [x] 4.2 Ajouter `GET /books/:id/progress` dans `read_routes`
+- [x] 4.3 Ajouter `PATCH /books/:id/progress` dans `read_routes` (accessible token read et admin)
+
+## 5. Swagger / OpenAPI
+
+- [x] 5.1 Dans `apps/api/src/openapi.rs`, enregistrer `ReadingProgressResponse`, `UpdateReadingProgressRequest` dans les `components(schemas(...))`
+- [x] 5.2 Enregistrer les paths `get_reading_progress` et `update_reading_progress` dans `paths(...)`
+- [x] 5.3 Vérifier que `BookDetails` mis à jour est correctement reflété dans le Swagger généré
