fix(mesh): ride out the radio restart during apply — no false errors, no setup modal

Applying RF settings deliberately restarts the radio daemon (~15-20s).
Two things treated that healthy, expected gap as a fault (operator,
2026-08-06):

- radio_state was single-shot: a query landing inside the restart
  window reported "The radio daemon did not answer the state query"
  for a restart that was working correctly. It now retries for ~30s
  and says the radio is restarting while it waits. A real device-level
  refusal (not an RNode) still returns immediately.
- The device-setup modal auto-opens for any detected-but-unconnected
  port, so the restart looked like a newly plugged stick and
  interrupted the apply. Apply and Reboot now suppress auto-detect for
  90s via mesh.suppressDeviceDetect().
