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").

 - `auto_play` — `true` to immediately play on the speaker
 - `vibe` — text description of the desired mood/vibe (e.g. "chill lo-fi beats", "upbeat party music"). Uses CLAP text embeddings to match tracks in the same vector space as audio.
 - `alpha` — blend factor between taste profile and vibe (default 0.5). `1.0` = pure taste profile, `0.0` = pure vibe match, `0.5` = equal blend. Ignored when no vibe is provided.
+- `profile` — named taste profile to use (default: "default"). Each profile has its own listening history and taste embedding.

+Named profiles let each household member get personalized recommendations without polluting each other's taste.

+```bash
+# Create a profile
+curl -X POST http://192.168.86.51:8321/api/profiles \
+  -H "Content-Type: application/json" \

+# Build taste profile manually
+curl -X POST "http://192.168.86.51:8321/api/admin/build-taste-profile?profile=antialias"
+```
+
+All endpoints are backward compatible — omitting `profile` uses the "default" profile. Events with no profile assignment (including all existing events) belong to "default".
