Unsent live samples were kept in memory only, so a reboot or a killed
process during a dead spot lost them. The queue is now saved to
files/telemetry_queue.json with AtomicFile, at most every 5 minutes and
only after a change (the flash is not written every 15 s), and at once
when the service stops; it is restored, oldest first and within the
2000-sample cap, when the service starts. A damaged file restores
nothing rather than failing. Tested on the emulator across a reboot.
