auth-bundle-1 Phase 3.5: handler IsAdmin -> router-wrapped RequirePermission

Phase 3.5 atomic conversion. The five legacy admin-gated handlers (bulk_revocation, admin_crl_cache, admin_scep_intune, admin_est, intermediate_ca) had their in-body auth.IsAdmin checks removed; the gate moved to router.go via auth.RequirePermission middleware wrapping each route. Non-admin operators with the right scoped permission can now reach these endpoints; legacy in-body admin checks no longer block them.

Migration 000030_rbac_admin_perms.up.sql ships five admin-only fine-grained permissions: cert.bulk_revoke, crl.admin, scep.admin, est.admin, ca.hierarchy.manage. All five are seeded into r-admin only; operator/viewer/agent/mcp/cli/auditor do not receive them by default. Operators can grant any of these to a custom role via the Phase 4 RBAC API. Idempotent + transaction-wrapped.

internal/domain/auth/validate.go::CanonicalPermissions extended with the five new entries so RoleService.AddPermission accepts them.

internal/api/router/router.go: HandlerRegistry gains a Checker field (auth.PermissionChecker). New rbacGate(checker, perm, handler) helper wraps a handler with auth.RequirePermission middleware; nil-checker fall-through preserves test/demo deployments without the RBAC stack. 12 admin routes wrapped: cert.bulk_revoke (POST /api/v1/certificates/bulk-revoke + POST /api/v1/est/certificates/bulk-revoke), crl.admin (GET /api/v1/admin/crl/cache), scep.admin (GET /api/v1/admin/scep/profiles + GET /api/v1/admin/scep/intune/stats + POST /api/v1/admin/scep/intune/reload-trust), est.admin (GET /api/v1/admin/est/profiles + POST /api/v1/admin/est/reload-trust), ca.hierarchy.manage (POST /api/v1/issuers/{id}/intermediates + GET /api/v1/issuers/{id}/intermediates + POST /api/v1/intermediates/{id}/retire + GET /api/v1/intermediates/{id}).

cmd/server/main.go: HandlerRegistry.Checker wired with the same authPermissionCheckerAdapter shim Phase 4 introduced for AuthHandler. Same adapter; one source of truth.

Handler bodies: removed eight in-body auth.IsAdmin checks across the 5 files. bulk_revocation.go's BulkRevoke + BulkRevokeEST, admin_crl_cache.go::ListCache, admin_scep_intune.go's three methods, admin_est.go's two methods, intermediate_ca.go's four methods. Replaced each with a comment naming the new gate location. Unused 'github.com/certctl-io/certctl/internal/auth' imports removed.

Test triplet rewrite: deleted obsolete _NonAdmin_Returns403 and _AdminExplicitFalse_Returns403 tests across 6 test files (5 handler tests + bulk_revocation_est_test.go) — they tested the now-removed in-body gate. _AdminPermitted_ForwardsActor tests stay intact: they pin the actor-passthrough invariant which is still relevant. Added internal/api/router/rbac_gate_integration_test.go with four router-level integration tests pinning the new gate: deny → 403 + handler not reached, permit → 200 + handler reached, nil-checker → fall-through, no-actor → 401.

M-008 admin-gate registry: AdminGatedHandlers map now empty (Phase 3.5 invariant: zero in-handler auth.IsAdmin call sites; only health.go's informational caller remains). m008_admin_gate_test.go retains the scan to enforce the invariant going forward; new admin-gated routes must wrap at router.go::rbacGate, not gate in-handler. Updated error message to direct future contributors to the new pattern.

Verifications: gofmt clean across all touched files; go vet ./... clean; go test -short across internal/auth, internal/service/auth, internal/api/handler, internal/api/router, cmd/server all green.

Branch: dev/auth-bundle-1. Commit chain: 99a012e (Phase 0 extract) -> 19497ee (Phase 1 schema + repo) -> bd54d5f (Phase 2 service) -> d473398 (Phase 3 primitive) -> b169f25 (Phase 4 + 5) -> THIS (Phase 3.5 conversion). Phase 6+ (bootstrap, scope-down, auditor, approval-bypass closure, GUI, docs) on subsequent sessions.
