MarekWo f352ccd968 fix(ble): add keepalive and robust reconnection for BLE zombie connections ...

BLE connections can enter a "zombie" state where notifications (reads) still
arrive but writes silently fail.  This went undetected until the user tried
to send a message, at which point the connection was already dead.

Additionally, after an abnormal BLE disconnect, BlueZ retains stale GATT
notification handles, causing reconnection to fail with
"[org.bluez.Error.NotPermitted] Notify acquired".

Changes:
- Add BLE keepalive loop (60s interval) that sends get_bat() to detect
  zombie connections proactively and trigger reconnection automatically
- Add adapter power-cycle (hci0 off/on via D-Bus) during BLE reconnection
  to clear stale GATT notification state
- Dedicated _ble_reconnect() with 5 attempts + adapter reset between each
- Health endpoint returns 503 when BLE permanently fails, triggering
  Docker container restart via healthcheck
- Guard against concurrent reconnection attempts
