feat: Add TCP connection support for Meshtastic

Browse Source 
Allow connecting to WiFi-enabled Meshtastic devices via TCP/IP in
addition to USB/Serial connections. This enables remote monitoring
of mesh nodes that have WiFi capability (T-Beam, Heltec WiFi LoRa, etc).

- Add connection_type parameter ('serial' or 'tcp') to /meshtastic/start
- Add hostname parameter for TCP connections
- Update UI with connection type dropdown and hostname input field
- Show connection type in status responses
