feat(channels): add multi-channel management UI with real-time connect/disconnect

- Web console Channels page: display active channels as config cards, support
  save/connect/disconnect with real-time start/stop of channel processes
- Custom dropdown for channel selection (consistent with model selector style),
  custom confirmation dialog for disconnect
- Fix channel stop: use sys.modules['__main__'] to access live ChannelManager
- Fix web request pending: move stop logic outside lock, set daemon_threads=True
- Fix reconnect: new asyncio event loop per startup, ctypes thread interrupt,
  5s grace period before re-establishing remote connection
- Filter stale offline messages (>60s) pushed after reconnect
