Fix TypeScript compilation errors

- Add searchReference to ApplicationListItem type
- Fix result variable in toApplicationDetails function
- Add query helper functions for req.query parameter handling
- Fix req.query.* type errors in routes (applications, cache, classifications, objects)
- Fix CompletenessCategoryConfig missing id property
- Fix number | null type errors in dataService
- Add utils/queryHelpers.ts for reusable query parameter helpers
