Mobile/accessibility: Missing alt text, difficult navigation

[personalizedrefrigerator]

Environment

Joplin version: d293474
Platform: Android 12
OS specifics: Samsung tablet (OneUI 4)

Steps to reproduce

1. (optional) Enable TalkBack captions (Settings → Accessibility → TalkBack → Settings → Advanced Settings → Developer Settings → Display speech output)
2. Enable TalkBack (Settings → Accessibility → TalkBack)
3. Open Joplin
4. Focus the 'edit note' button
5. Focus the 'back' button
6. Focus the 'search' button
7. Focus the 'show sidebar' button
8. Focus the 'search sorting' button
9. Focus the '+' button
10. Focus the '☐' button to the left of an incomplete note
11. Open the sidebar
12. Focus the icon to the left of the 'Notebooks' header in the sidebar
13. Open 'configuration'
14. Attempt to left/right swipe to the 'language' setting.
15. After (14) fails, attempt to focus the 'Language' setting by tapping on 'Language'
16. Save settings

Describe what you expected to happen

1. All buttons should have meaningful alt text.
2. Clicking configuration should focus the configuration component.
3. Using explore with touch to select items in the configuration component should not select items in the (invisible) sidebar.
4. It should be possible to save after changing settings
   • Perhaps a confirmation dialog when the user presses their device's back button (e.g. there are unsaved changes. Save them? (Yes) (No)), allowing users to save settings when closing the configuration window.
5. WebViews containing note content should have meaningful labels (currently, the screen reader just reads WebView)
   • Labels on WebViews allow users to know what the WebView contains before navigating into it.
