An operator who triggers `ota update` via remote management only sees the
command's reply; the actual OTA runs ~2.5s later and reboots on success,
so the start/fail notifications land outside the reply window. Mirror the
key OTA milestones onto the configured alert channel (in addition to the
Serial log):
- START ("OTA update starting") from beginDeferredOtaUpdate(), i.e. while
the loop still runs -- a flood queued at the deferred fire could never
transmit before the flash blocks the loop / reboots on success.
- FAIL ("OTA aborted: ...") at both abort points (teardown barrier
withheld flashing; preflight/download error).
Success has no message: a successful flash reboots into the new image, so
the node returning on the new version is the signal.
New MyMesh::otaAlert() gates on the `alert on/off` master switch and rides
the configured alert scope (AlertReporter::sendText -> sendChannel ->
resolveAlertScope); no-op when alerts are off or no channel is set. Only
these start/fail milestones -- routine slot connect/disconnect is
unaffected (stays in AlertReporter's fault logic). Documented in ALERTS.md.
Both observer firmwares build.
