feat: replace SSE client with direct TCP/WiFi connection

Browse Source 
- Remove SseClientService and ConnectionMode.sseClient
- Add ConnectionMode.tcp with MeshCoreTcpService (port 5000)
- NetworkScannerService: scan TCP port 5000 via raw Socket.connect
- mDNS service type changed to _meshcore._tcp
- connection_dialog: connect via connectTcp() instead of connectToSseServer()
- home_screen: show WiFi icon and label for TCP mode
- Bump meshcore_client to pick up TCP transport support
