PostgreSQL-Integration: Rahmenprogramm-Slot mit verschachtelten `phases` (Blueprint-Unit).

Aktivierung:
  - Lokal: TRAINING_PLANNING_INTEGRATION=1
  - CI: .gitea/workflows/test.yml setzt die Variable beim pytest-Lauf.

Prüft `_insert_slots_and_blueprints` → `_replace_unit_phases` wie beim API-PUT mit Slot-Payload.
