Phase 3 Week 7: Add KOReader database queries and generated code

- Add GetMediaItemByFilePathForSync for file path matching
- Add GetUserProgressForBooks for bulk progress retrieval
- Add GetAnnotationsForBook for annotation sync
- Add UpdateDeviceSyncTimestamp for device tracking
- Add GetUserMediaItemsForSync for library sync
- Add CheckForProgressConflicts for conflict detection
- Regenerate sqlc code for all new queries
- Part of Phase 3 KOReader Integration implementation
