After radio_offline_threshold consecutive send timeouts the bot enters radio-offline state and every send path refuses to transmit. The only thing that cleared it was _record_send_success, which runs after a send goes out, so once offline the bot stayed offline until restarted. The web viewer's Clear Offline Flag could not help either: the viewer runs in its own process, so it only wrote bot_metadata, which the bot never read back.
Three paths now clear the state: a health probe the radio answers, a successful (re)connect, and the health loop noticing that bot_metadata says the flag was cleared. The new tests for the probe and viewer paths fail without the change.
