Make repeater RX watchdog MeshCore-aware and tune temporary radio

Use RX-only radio recovery and feed the repeater reboot watchdog after MeshCore parsing. Default to 24 hours, apply temporary watchdog and advert intervals in RAM, and report temporary durations as days, hours, and minutes. Add regression coverage and an ESP-NOW bridge setup guide.
