Add named taste profiles for per-person recommendations

Named profiles allow each household member to get personalized
recommendations without polluting each other's taste. Includes
profile CRUD API, speaker→profile auto-attribution, recent listen
history endpoint, and profile param on all existing endpoints.
All endpoints backward compatible (no profile param = "default").

+## Named Profiles
+
+Named profiles allow per-person taste tracking. No auth — just named buckets.

+- **Default behavior**: All endpoints without `profile` param use the "default" profile (backward compatible)
+- **Profile CRUD**: `GET/POST /api/profiles`, `GET/DELETE /api/profiles/{name}`
+- **Speaker mappings**: `PUT/GET /api/profiles/{name}/speakers` — auto-attributes listen events from mapped speakers
+- **Attribution**: Webhook accepts `"profile": "name"` or auto-resolves from speaker→profile mapping
+- **Recommendations/playlists**: Pass `profile=name` to use that profile's taste
