Merge upstream/main: sync fork with conflict resolution

Resolve conflicts keeping local GSM tools in kill_all() process list
and weather satellite config settings while merging upstream changes
including GSM spy removal, DMR fixes, USB device probe, APRS crash
fix, and cross-module frequency routing.
