admin: delegate capabilities and access routes

TASKS.md

@@ -156,4 +156,5 @@ Progress:
   - Phase 0 / task `0.12`: `apps/admin-api` и `apps/mcp-server` переведены на `community_default().with_limits(...).with_response_cache(...).build()` вместо прямой сборки runtime через `RuntimeExecutor::with_limits(...)`
   - Phase 0 / task `0.13`: введены `RegistryExtension`, `ExtensionMigration` и `apply_extension_migrations(...)` в `crank-registry` как отдельный public seam для additive private migrations
   - Phase 0 / task `0.14`: добавлены `AdminServiceBuilder`, seam slots (`identity_provider`, `policy_engine`, `audit_sink`, `token_issuer`, `capability_profile`) и community defaults для них; `apps/admin-api/src/main.rs` переведен на builder
+  - Phase 0 / task `0.15`: начат route delegation pass — `capabilities` route идет через `capability_profile`, а write handlers в `routes/access.rs` проверяют `policy_engine` и пишут generic audit events через `audit_sink`; `machine_auth` часть остается pending до actor-aware auth wiring
   - backward-compatible alias `CommunityMachineCredentialVerifier` сохранен, поведение Community не изменено
