feat: diarisation des locuteurs en temps réel (ECAPA-TDNN + clustering incrémental)

- Nouveau module diarizer.py : EmbeddingModel (SpeechBrain ECAPA-TDNN) + SpeakerDiarizer par session
- Backend : chargement modèle au lifespan, migration DB (colonne speaker), worker enrichi, exports avec locuteur
- Frontend : badges locuteurs colorés (8 couleurs), toggle activation, copie avec [Locuteur X]
- Config : DIARIZATION=on/off, DIARIZATION_THRESHOLD=0.70, PyTorch CPU-only dans Dockerfile
- Rétrocompatible : désactivé par défaut (DIARIZATION=off)
