feat(mobile): darken screen on backup page

[Saschl]

Follow up of: #11621, will darken the screen when starting the backup to avoid burn-in issues.

I've decided to create 2 separate PRs as this one will likely take a bit longer as I need some feedback on how to implement this best UX wise.

Tested with Android emulator (Pixel 8), iOS Emulator (iPhone 15) and iPhone15 Plus, OnePlus 3T (real devices)

Current idea (sped up, actual timeout is 60 seconds), open for feedback :)

I think we don't need to show the confirmation form here. When the backup process start, we start a timer, after 1 minutes then we auto darken the screen

Sounds fine, applied the changes and removed the dialog.

can we refactor this to a method so we don't duplicate code on line 306?

Thank you for the contribution again! I tried it and like it a lot. One small request: Can we make the screen darken to a certain level, not completely dark? Think of an always-on mode screen shade so the user can still see what is happening?

Thanks for taking care! I initially chose to turn the screen black completely oled displays will essentially be off and avoid burn ins. But I’m not even sure if that’s a thing anymore.
