feat: auto-detect and enable mesh radio on startup

Browse Source 
When no mesh config exists (fresh install), scan for serial devices
at /dev/ttyUSB* and /dev/ttyACM*. If a radio is found, auto-enable
mesh and save the config so subsequent boots connect immediately.

Previously, mesh defaulted to disabled and the radio was never probed
unless the user manually created a mesh-config.json file.
