refactor(settings): deprecate settingsKnownSchema and integrate bird and revision settings

- Merged birdSettingsSchema and revisionSettingsSchema into settingsKnownSchema, marking the previous schema as deprecated.
- Updated emptySettingsKnownForm to utilize emptyBirdSettingsForm and emptyRevisionSettingsForm.
- Refactored layout and page components to streamline theme management and improve tab synchronization in network and operations pages.
- Introduced new system settings tab in operations and updated settings page to manage theme preferences.
