Förslagsmotorn: Generera-knapp, schema, diskcache och bläddringssida

- suggest.js: samlar signaler (Lidarr-bibliotek, Jellyfin senast spelat,
  Youtubarr-DB senast tillagt/gillat via better-sqlite3 ro), bygger svensk
  Gemini-prompt (JSON-svar), berikar förslagen med MBID/omslag via Lidarrs
  metadata-API, cachar batcher i /data/suggestions.json
- API: POST /api/suggest/run, GET latest (10 senaste till Upptäck),
  GET batches + batches/:id (bläddring)
- Schemaläggare i server.js: kollar var 10:e minut mot inställningen
  suggest.intervalHours (default 24, 0 = av) — ställs in under ⚙
- Upptäck: senaste 10 som kort med motivering + '✨ Generera nya förslag';
  ny Förslag-sida bläddrar alla cachade batcher; delat MusicCard-kort
  (sök + förslag) med Hämta-knapp
- Dockerfile: byggverktyg för better-sqlite3; 4 nya tester, totalt 25
