test(api): fill router auth and security coverage gaps

Four new test files — 27 tests total:
- role-router-auth.test.ts (8): UNAUTHORIZED/FORBIDDEN on all mutations for
  unauthenticated/USER callers; MANAGER and ADMIN happy paths
- webhook-router-auth.test.ts (6): adminProcedure guard verified for all
  six webhook procedures across USER/MANAGER/ADMIN roles
- comment-sanitization-router.test.ts (4): proves stripHtml runs before
  db.comment.create — script tags stripped, plain text and @mentions preserved
- auth-anomaly-check/route.test.ts (+5 unit tests): detectAuthAnomalies()
  unit coverage — empty window, global threshold, per-entity threshold, null
  entityId, and both anomaly types firing simultaneously
