Web commands are answered once queued, but the main loop handed all of
them to the radio at once and anything past its free slots was dropped
silently. Unpair also cleared paired even when the Prog wasn't sent.
- processQueue leaves commands queued until the radio has room.
- Commands that transmit get a 503 straight away during a frequency
scan instead of being dropped later.
- Unpair restores paired when the Prog can't be sent.
- Failed web commands are logged.
- Note that /setPositions and /setSensor answer with the state before
the command; the socket events carry the result.

- endFrequencyScan always resumes TX; applying radio settings ends a scan.
- Frequency scans time out after 5 minutes.
- Reboot when an OTA upload is abandoned mid-transfer.
- /sendRemoteCommand returns 503 when the radio can't take the frame.

- Abort in-flight transmissions on flush so config save, frequency scan
and OTA never wait on the radio lock for a whole job
- Suspend TX during frequency scan and OTA
- Refuse commands the radio queue cannot take before consuming a rolling
code or moving simulated shade state; shift movement start when a job
goes on air late
- Apply radio config changes under the radio lock
- Re-check receiver idle before repeater transmissions
- Return 503 from web handlers when the command queue is full
- Restore 200 ms settle delay before the set-My command
- Report RSSI 0 instead of a stale value when the radio is busy
- Encode each frame once and centralise the repeat clamp

Web command handlers ran on the async_tcp task and blocked up to 3s
waiting for loop() to bit-bang radio frames. async_tcp also services the
WebSocket on port 8080, so pongs stalled and Home Assistant
(ping_timeout=15) disconnected when several covers were commanded.
- Add a radio_tx FreeRTOS task with a job queue; sendFrame/repeatFrame
and repeater frames enqueue instead of transmitting inline.
- Serialize CC1101 access with a recursive mutex (TX task, apply, end,
frequency scan, RSSI read).
- Make Web::queueCommand fire-and-forget; drop the done semaphore.
- Route /setMyPosition and /unpairShade through the command queue.
- Clamp repeats to MAX_TX_REPEATS (40).
- Pin AsyncTCP to core 0 on dual-core targets.
