Jannis Braun 024833c470 fix: security hardening and Safari stability ...

- Remove hardcoded JWT_SECRET fallback (crash on boot if unset)
- Make LiveKit config optional with 503 guard on token endpoint
- Add REST rate limiting via @fastify/rate-limit (auth 10/15m, messages 5/5s, uploads 10/1m, global 60/1m)
- Add WebSocket token bucket rate limiter (30 burst, 2/sec refill)
- Add DM channel ownership (ownerId) with migration, enforce on add-member
- Require friendship to add users to group DMs
- Add silent 20Hz oscillator to prevent Safari AudioContext suspension
- Move WebSocket heartbeat to Web Worker to bypass Safari background throttling
