* added vehicle command and support to remotely activate/deactivate the safety system (#26078)
* added print_status support for prearm safety status
* updated safety button to map to MAV_CMD_DO_SET_SAFETY_SWITCH_STATE = '5300'
* safety switch cmd: fixed incorrect catch-all and added commanded_state variable for easier reading
The safetyButtonHandler() reports that the safety statatus
changed on the first loop iteration when safety is disabled which makes
sense to inform the system that safety is off but the tune for the user
should not be played because it interrupts the startup tune.
