+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.
