BUILD_RTI=OFF: CODEGEN_* Makros in IF-Blocekt + DatabaseInterfaceImpl Stubs

- Alle 38 Service-Module CMakeLists.txt: CODEGEN_* Makros in IF(BUILD_RTI) gepackt
- flm_db_impl_custom.h: Include-Pfad korrigiert (Lts/Services/... → FileManagement/)
- DatabaseInterfaceImpl Stub-Header erstellt für:
  - FileManagement (flm_db_impl.h)
  - InfrastructureManagement (ism_db_impl.h)
  - ParticipantManagement (ppm_db_impl.h)
  - RecordingManagement (rec_db_impl.h)
  - Evaluations (evl_db_impl.h)
- opm_enums.hpp: Placeholder-Enums für OperatorManagement

Ermöglicht BUILD_RTI=OFF Builds ohne RTI/DDS Codegenerierung
