feat(#240): backend for Mission Control Strip — queue endpoints + expert flag
Adds the server-side foundation for the dashboard transcription widget:
- V36 migration: needs_expert BOOLEAN NOT NULL DEFAULT FALSE on documents
- Document entity: needsExpert field (@Schema required)
- DocumentRepository: 4 native queries — segmentation queue, transcription
queue, ready-to-read queue (seeded weekly shuffle sort), weekly pulse stats
- TranscriptionQueueService: maps Object[] rows to typed DTOs, handles
PostgreSQL type variations (UUID/String, Date/LocalDate, Number/BigDecimal)
- TranscriptionQueueController: GET /api/transcription/{segmentation-queue,
transcription-queue, ready-to-read, weekly-stats} — all guarded by READ_ALL
- DocumentService + DocumentController: PATCH /api/documents/{id}/needs-expert
toggles the expert flag (WRITE_ALL required)
