feat: auto-save ciblé au blur avec feedback violet sur tous les champs

- Nouvelle action updateDimensionScore pour sauvegarder un seul champ
  en base sans envoyer tout le formulaire
- DimensionCard : blur sur notes, justification, exemples, confiance
  → upsert ciblé + bordure violette 800ms
- CandidateForm : même pattern sur tous les champs du cartouche
- Bouton save passe aussi en violet (cohérence visuelle)
