fix: Add serial port discovery for Meshtastic multi-port systems

Browse Source 
When multiple serial ports are detected (e.g., /dev/ttyACM0 and /dev/ttyUSB0),
the Meshtastic SDK's auto-detect fails. This adds a /meshtastic/ports endpoint
to list available ports and populates the device dropdown, auto-selecting the
first port when multiple exist.
