fix: implement proper applesauce relay pool query pattern

- Replace addressLoader with direct relayPool usage
- Use relayPool.query() with proper filter for kind:10003 events
- Add RelayPool import to Bookmarks component
- Update TypeScript interfaces to use RelayPool instead of addressLoader
- Follow applesauce documentation pattern for querying events
