Keep bridged OTA retries resumable across profile handoffs

Let the mesh timed OTA retry guard own byte-identical requests instead of the permanent bridge FIFO. Bind bridge ingress to its primary profile generation and preserve UART reflection/liveness protections. Verified a LoRa to ESP-NOW to LoRa update with outage recovery and install.
