feat(controls): B3 — categorize the rest of needs_tooling (architectural + RBAC)

Closes out B's coverage of the 16 needs_tooling CRA controls:

- cra-ai-2,3,4,5 (minimal attack surface, secure architecture, least-privilege,
  tamper protection) are design properties, not local code patterns -> marked
  not_code_checkable (out of static-scan scope) with reviewer notes.
- cra-ai-12 (RBAC) is surface-checkable (authorization points) -> added to the
  grounded surface pass; note points to the gated grounded mechanism.

Final CRA coverage: covered 13 | needs_tooling 8 (all grounded-covered, gated) |
not_code_checkable 19. The 16 needs_tooling now fully categorized:
4 custom-semgrep (B1) + 8 grounded surface (B2/B3, gated) + 4 architectural (B3).
