Redo onboarding persistence
- First, check if already persisted
- If not and chrome, go to new notifications requesting page with fail states that don't continue
- Actions like adding to home screen may already enable persistence, which we checked for in step 1. In that case this step is automatically skipped
- Else, go to new persistence requesting page (firefox), also with fail states that don't continue
- If the user uses desktop safari, tell them to "add to dock" or switch browsers
