fix: resolve TypeScript errors in database service implementation

- Remove unnecessary generic type parameter from AbsurdSqlDatabaseService
- Fix type handling in operation queue and result processing
- Correct WebPlatformService dbGetOneRow implementation to use imported databaseService
- Add proper type annotations for database operation results

This commit improves type safety and fixes several TypeScript errors that were
preventing proper type checking in the database service layer.
