v1.9.2: Fix hotspot non démarré si SQLite lockée au boot

- boot_hotspot.sh: busy timeout 5s sur les requêtes SQLite
- boot_hotspot.sh: SSID fallback nebuleair-pro-<serial> si deviceName vide
- Corrige le cas où le hotspot ne démarrait pas quand la DB était
  lockée par les timers systemd au boot (SSID vide → nmcli refuse)
