feat: add job runs chart and scrollable reading lists on dashboard

- Add multi-line chart showing job runs over time by type (scan,
  rebuild, thumbnails, other) with the same day/week/month toggle
- Limit currently reading and recently read lists to 3 visible items
  with a scrollbar for overflow
- Fix NUMERIC→BIGINT cast for SUM/COALESCE in jobs SQL queries

+## Notifications
+
+### Telegram
+- Real-time notifications via Telegram Bot API (`sendMessage` and `sendPhoto`)
+- Configuration: bot token, chat ID, enable/disable toggle
+- Test connection button in settings
+
+### Granular Event Toggles
+12 individually configurable notification events grouped by category:
+
+| Category | Events |
+|----------|--------|
+| Scans | `scan_completed`, `scan_failed`, `scan_cancelled` |
+| Thumbnails | `thumbnail_completed`, `thumbnail_failed`, `thumbnail_cancelled` |
+| Conversion | `conversion_completed`, `conversion_failed`, `conversion_cancelled` |
+| Metadata | `metadata_approved`, `metadata_batch_completed`, `metadata_refresh_completed` |
+
+### Thumbnail Images in Notifications
+- Book cover thumbnails attached to applicable notifications (conversion, metadata approval)
+- Uses `sendPhoto` multipart upload with fallback to text-only `sendMessage`
+
+### Implementation
+- Shared `crates/notifications` crate used by both API and indexer
+- Fire-and-forget: notification failures are logged but never block the main operation
+- Messages formatted in HTML with event-specific icons
