Allow in-flight disarming via controller without triggering emergency…

… stop

This commit updates the client to allow users controlling their drones with physical controllers to disarm the drone mid-flight. Previously, the disarm button on controllers was explicitly linked to triggering an emergency stop, preventing standard disarming during flight.

With this change, pressing the disarm button on the controller will now safely disarm the drone, rather than activating an emergency stop. For emergency situations, users should continue using the dedicated emergency stop function, which is more reliable for halting the drone immediately.

The (dis)arm controller button is still linked to crash recovery.

UI arm/recover/emergency-stop button behavior is unchanged.

Use together with bitcraze/crazyflie-firmware#1426
