feat: complete Vue UI parity (full backend + frontend)

== New domain models (7) ==
- UserPermission: per-user feature toggles (13 booleans)
- StorageConfig: encrypted Alist/S3/WebDAV adapters
- LicenseKey + LicenseActivation: offline license issuance
- DownloadClient: multi-client downloader configs
- AssistantSession + AssistantMessage: multi-turn AI chat persistence

== New services (5) ==
- PermissionService: admin grants always-true; user defaults seeded
- StorageConfigService: AES-GCM encryption + per-type connection probe
- LicenseService: 24-char hyphenated key generation, activation/heartbeat
- DownloadClientService: qB/Aria2/Transmission CRUD + WebUI test
- AssistantService: chat history + execute/undo stubs (op_id tracking)

== Extended AIService.Chat ==
- Multi-turn LLM call with chat history; offline fallback reply

== New endpoints (60+) ==

== New React pages (4) ==
- AssistantChatPage (/assistant): full multi-turn chat UI with sessions
  sidebar, optimistic user-turn append, live AI response.
- DownloadClientsPage (/download-clients): typed CRUD form for
  qBittorrent / Aria2 / Transmission + per-row Test action.
- LicensePage (/license): generate keys, list activations, revoke,
  unbind individual devices.
- StorageConfigPage (/storage-config): tabbed Alist/WebDAV/S3 form
  with secret-aware redaction + connection probe.

== New API helpers (5) ==
- assistant, download_clients, license, permissions, storage_config

== Layout ==
- Sidebar gains 4 new admin links (AI 对话, 下载器, 外部存储, 许可证).
