Add Skip Forever, app icon, About screen links, release signing

- Add Skip/Skip Forever links to onboarding screens only
- Remove Skip links from questionnaire screens (baseline, behavioral, lifestyle)
- Add app icon (1024x1024) and generate all platform sizes
- Update About screen with correct URLs (privacy, terms, disclaimer, how it works)
- Add "No ads. Ever." section to About screen
- Configure Android release signing with upload keystore
- Add URL intent query for Android 11+ link launching
- Add skipForever preference to LocalStorage
