- Service `app/services/test_templates.py`: CRUD with MITRE tag resolution
(kind, external_id) → polymorphic join, filters by tactic/technique/
subtechnique/opsec/tag, `_UNSET` sentinel for partial-update semantics.
- Service `app/services/scenario_templates.py`: ordered test list, reorder
via full-replace (atomic w.r.t. UNIQUE(position) constraint), soft-delete.
- REST endpoints on /api/v1/test-templates and /scenario-templates with
pydantic schemas + perm gating (test_template.* and scenario_template.*).
- /diag/reset truncates the 4 new tables before MITRE (FK ordering).
- 19 pytest covering CRUD, MITRE tag merge, soft-delete chaining, perm
enforcement, and reorder atomicity.
