fmt all

- merge /api/uptime + /api/version into /api/health and /api/stats
- collapse RTMP per-codec dispatch into a single CodecParser path
- dedupe STUN attribute walking (ufrag_pair / parse_xor_mapped_address)
- dedupe StreamCodec <-> str0m Codec mapping via StreamCodec::from_str0m
- dedupe bearer token extraction in WHIP handlers
- replace regex charset validation with stdlib checks
- flatten one-field wrappers (WebRtcProxyConfig, HttpServerConfig, ServerInfo)
- remove SessionCookie extractor (only fed debug logs)
- delete dead code: entity ActiveModel helpers, get_stream_session,
  WebrtcProxy::local_addr, _connected flag, commented-out blocks
- drop unused deps: futures, rand, regex, serde_json
