Replace DragonflyDB with Valkey throughout codebase

- Update all DragonflyDB references to Valkey in README and docker-compose.yml
- Update install instructions to use Valkey package repository and .deb download
- Update configuration paths from /etc/dragonfly/ to /etc/valkey/
- Update version requirement to Valkey 8.x+ (successor to Redis OSS)

 ### 4. Cache layers (Redis + CDN)
 
-The CMS caches through `cached()` / `cachedQuery()` (`src/lib/cache.ts`): an in-memory fast path with a Redis (DragonflyDB-compatible) fallback and single-flight protection against cache stampedes. Public API routes (home, leaderboard, online count, radio, photos, …) fill Redis keys per route; verify with `redis-cli DBSIZE`. With Cloudflare in front, static and `/imaging/*` responses are additionally cached edge-side (`cf-cache-status`), cutting origin load further.
