feat: Add saved filters to backup and restore

This commit adds support for backing up and restoring saved filters.

- Added a new `SAVED_FILTERS` section to the backup process.
- Implemented the logic to read filters from SharedPreferences during backup and write them back during restore.
- Fixed compilation errors in `AppBackupAgent` and `BackupSectionModel`.
