Error flags byte 66: implementation RTC flags + escalade PDP reset → hardware reboot

- Constantes error_flags (byte 66) + methodes SensorPayload
- Construction byte 66 avec flags RTC (disconnected/reset)
- Escalade: si PDP reset echoue apres echec UDP → notification + hardware reboot + exit
- Doc: ajout byte 68 device_status (specification)
