feat: Tier 1 & 2 — Daily Note, Voice, Flashcard quota, Readwise, Calendar, Agent Gallery

Tier 1:
- BASIC tier: chat (10/mo) + reformulate (10/mo) désormais accessibles
- Nouveaux quotas: ai_flashcard + voice_transcribe dans tous les tiers
- /api/notes/daily : note du jour auto-créée (find or create)
- Bouton Note du Jour dans la sidebar (CalendarDays)
- Voice-to-Text dans l'éditeur (Web Speech API, bouton Mic toolbar)
- Flashcard generation → quota ai_flashcard (au lieu de reformulate)

Tier 2:
- Intégration Readwise: GET/POST/DELETE /api/integrations/readwise
- Intégration Google Calendar: OAuth flow + today's events + meeting notes
- /api/integrations/calendar + /callback
- Page /settings/integrations avec cards Calendar + Readwise
- SettingsNav: onglet Intégrations
- AgentTemplates: catégories + 4 nouveaux templates (Digest/Recap/AutoTagger/Synthesis)

Schema:
- UserAISettings.integrationTokens Json? (migration 20260529160000)
- prisma generate + migrate deploy appliqués

Fix:
- SpeechRecognition types (triple-slash @types/dom-speech-recognition)
- Notebook.create: suppression champ 'description' inexistant
