fix: Resolve TalkBack accessibility issues

[MarcaDian]

Fixes the four accessibility issues:

1. Auto-install toggle now exposes on/off state to TalkBack.
2. Expanded patch source cards keep inner controls focusable by moving the click target onto the header only.
3. Simple Mode - progress is reported through a single polite live region throttled to 10% steps, and the constantly-updating progress widgets are silenced.
4. Apps on the home screen can be reordered with a screen reader via Move up / Move down accessibility actions.

Can't wait to test the improvements. I'm really, really excited!

I apologize for not looking into the issue sooner. That was my mistake. I know how annoying it is to have to repeat things, so thank you for just pointing out the error and handling it for us.
