Incorrect handling of Non-Zotero annotations. Some are vanishing on tap, while others are allowed to edit.

I was able to reproduce it by annotating a PDF with MacOS’s pdf editor and then uploading to Zotero.
Turns out it happens consistently whenever non-zotero annotation is getting tapped. Text and ink annotations vanish.
Other annotations allow themselves to get edited, but changes are not saved.

On iOS and Web some non-zotero annotations types are not tappable, while others are, but AnnotationEditing screen has a Lock icon and any input fields disabled.

As I look through code I realize that non-zotero annotation handling hasn’t been yet implemented on Android.
So to fix this we should just implement it.
