Clean up Xbox proxy: Remove obsolete Caddyfile and improve docs

- Remove Caddyfile (Python proxy handles everything)
- Clarify that REQUEST body is filtered, not response
- Add better log examples showing actual output
- Add docker-compose comments about port exposure
- Explain filtering flow: User-Agent detection → JSON parsing → Codec filtering

+Der Proxy interceptiert `POST /Users/*/Items/*/PlaybackInfo` Requests:
+1. Erkennt Xbox via `User-Agent: ... WebView2 Xbox`
+2. Parsed den JSON Request-Body
+3. Filtert AV1 aus VideoCodec und Opus aus AudioCodec
+4. Sendet modifizierten Request an Jellyfin
