 Minimal-CRUD für Plan-Templates & Pläne (POST/GET) + Idempotenz via Fingerprint.
-Erweiterungen:
-- optionale Section-Felder ideal/supplement + materialisierte Facettenfelder
-- Referenz-Validierung: template_id (pflicht, wenn gesetzt)
-- Optionaler Strict-Mode: PLAN_STRICT_EXERCISES prüft exercise_external_id
+NEU in v0.12.0:
+- List-/Filter-Endpoints: GET /plan_templates, GET /plans
