Updates to automatic rule pages in Settings

- Re-added metrics for zen behavior preference controllers
- Dialogs in zen mode settings are rotate-friendly
- Automatic rules are refreshed on update state
- User-created (and default) automatic rules are always priority only and user cannot change this
- Automatic rules redesigned to have headers
