refactor: use databaseUtil.updateDefaultSettings for feed filter settings

- Replace direct platform service calls with databaseUtil.updateDefaultSettings
- Remove manual SQL query construction in favor of centralized utility
- Improve code consistency and maintainability
- Add proper error handling through databaseUtil's built-in mechanisms
- Remove unused PlatformServiceFactory import
- Fix SQL syntax errors in clearAll and setAll methods (AND -> comma)
- Ensure both SQLite and Dexie databases are updated consistently

Improves: FeedFilters component architecture and error handling
Fixes: isNearby and filterFeedByVisible settings not being saved properly
