Persistent notification to allow app to run in the background

[jdrch]

Is your feature request related to a problem? Please describe.

If you use your Flipper Zero to store and emulate keys, you'll find that every time you open the app to use it for that purpose, you have to wait for it to connect to the Flipper Zero via Bluetooth. It would be nice if the app could persist in the background to keep that connection live. The best way to do that on Android is to create a persistent notification. See Resilio Sync and Tasker for implementation ideas.

Describe alternatives you've considered

I've tried disabling battery optimization for the app, but it still gets killed and/or loses Bluetooth in the background.

Additional context

I use my Flipper Zero as a universal remote control for various SubGHz remote outlets, switches, and controls in my house. Therefore, it's important to me that the app be ready to be used for that purpose when I open it.
