Display drone connect progress bar on reboot

[Turnlings]

Add the connection progress bar to the reboot autopilot modal. Replaces the default loader when connecting.

@1Blademaster is this what you were after? Is it also worth making it so that it replaces the normal loading circle when connecting so there aren't two loading symbols, might make it look cleaner.

Yeah makes sense to replace the normal loading circle 👍
