feat(firmware): runtime PHY lock + drop post-TX self-RX on announces

Browse Source 
- "LOCK:<T|C|R>" serial command pins the radio to one PHY for debugging /
  focused RX testing; "LOCK:" resumes the normal RTC scan
- clear rxFlag after a Reticulum announce TX so the TX-done interrupt no longer
  makes the bridge log a phantom "reception" of its own packet
