Pro Exhaust valve control

Hi, could be usefull for who have the Pro Exhaust (Mini or BMW) to have shortcut on the screen which render a script on the phone:

- save the current connected access point
- disconnect and connect the phone to defined access point
- get the relay status and trigger the relay (http api call)
- display a notification which say for ex. "valve closed"
- reconnect to the saved access point.

here my work on the valve relay:

No repository files, tests, or entry points are identified in the issue. Start by reviewing the Kotlin app structure and the linked JCW-Pro-Exhaust-Controller project, then determine where a shortcut can coordinate Wi-Fi switching, relay API calls, notifications, and reconnection. Done means the Pro Exhaust valve can be controlled through the requested on-screen flow.
