SegmentationTrainingExportService and TrainingDataExportService each injected
TranscriptionBlockRepository, AnnotationRepository and DocumentRepository
directly. They now go through:
- TranscriptionBlockQueryService (extended) for the three eligible-block
queries — used over TranscriptionService to keep
SenderModelService → TrainingDataExportService → TranscriptionService cycle-free.
- AnnotationService.findById (new) — read API on the annotation domain.
- DocumentService.findById (already added in #417 commit 3).
The TrainingDataExportServiceTest @DataJpaTest delegates the new service reads
to the real JPA repositories via Mockito stubs in the new makeService helper,
so the integration coverage stays unchanged.
