BIZ-52 Step3 开发实现: - storage: backend/usage/cooldown/config CRUD with SQLite WAL - crypto: AES-256-GCM API key encryption - pool_manager: primary/fallback pool routing - cooldown_manager: 429 exponential backoff cooldown - rate_limiter: per-backend token bucket RPM control - router: model → backend routing with pool priority - proxy: multi-pool request forwarding with retry - server: FastAPI admin API + OpenAI-compatible proxy + SSE - dashboard: WebUI with provider CRUD, stats, charts Co-authored-by: multica-agent <github@multica.ai>
