fix: bridge port is 4403, not 4003 (v0.1.1)

meshtastic-serial-bridge listens on TCP 4403; update MESH_PORT default
in mesh.service.ts, docker-compose.yml and docs.

+## v0.1.1 — 2026-09-23 19:38
+
+- Fixed the default bridge port to `4403`, the meshtastic-serial-bridge's actual TCP port (the old value pointed at a closed port). Updated the `MESH_PORT` default in code, the docker-compose environment, and docs.
+
 ## v0.1.0 — 2026-09-23 18:54
 
 - New `GET /api/channels` endpoint listing the device's Meshtastic channels as `{ index, name, uplinkEnabled, downlinkEnabled }`; psk/keys are redacted and never exposed over HTTP. Channels are collected from `FromRadio.channel` frames streamed during initial sync (before `config_complete_id`) and reset on every bridge reconnect so stale data is dropped after a disconnect.
