feat: implement long-tap gesture for patcher screen & fix metadata loading errors

1. Feature
It would be a time saver to have a button here on the patching page that takes you directly to the homepage with one tap, instead of tapping multiple times the back button to get to the homepage:

2. Bug

For your first request, I’ll make it so long-pressing the in-app back button (top left) returns you to the home screen. A normal tap will keep the current behavior and go back to the previous screen. I’ll also look into fixing the issue from your bug report. Thanks again!
