Refactor user repository fields management and enhance query structure

- Moved the `FIELDS` constant from `UserRepository` to `UserRepositoryInterface` to improve consistency and sharing.
- Updated SQL queries to include new fields (`absenceStart`, `mainLanguage`, and `isRoleSeeAuditTrails`).
- Streamlined CSV export logic to reference the shared `FIELDS` constant.
