feat: enhance Weixin channel support and configuration

- Added tests for listing Weixin channel catalog and retrieving dynamic Weixin instance configurations.
- Implemented Weixin channel handling in the backend, including validation and parsing of channel names.
- Updated Weixin flow handling to support multiple instances and added error handling for invalid channel names.
- Enhanced frontend components to allow creation of new Weixin channels with validation and error messages.
- Updated localization files to include new strings for Weixin channel management.
- Added unit tests for Weixin configuration management to ensure proper handling of multiple channels and type conflicts.

 ### Configuration Fields
 
 | Field | Description |
 |---|---|
 | `enabled` | Set to `true` to enable the channel at startup. |
 | `token` | The authentication token obtained via QR login. |
+| `account_id` | (Optional) Stable account identifier returned by QR login. Used to keep per-account state files stable. |
 | `allow_from` | (Optional) List of WeChat User IDs permitted to interact with the bot. If empty, anyone who can send messages to the connected account can trigger the bot. |
 | `proxy` | (Optional) HTTP proxy address (e.g. `http://localhost:7890`) for environments where connection to `ilinkai.weixin.qq.com` is restricted. |
 
 ## ⚠️ Important Notes
 
-- **One Account Only**: The iLink token binds to a single session. Starting a new interaction generally invalidates older tokens if another device authorizes.
+- **One token per account**: Each iLink token binds to a single WeChat account session. Bind multiple accounts as separate channels.
 - **Message Rate Limits**: To avoid getting your account restricted by WeChat anti-spam systems, avoid loop triggers or high-frequency broadcasts.

 | 字段 | 说明 |
 |---|---|
 | `enabled` | 设置为 `true` 以在启动时激活该频道。 |
 | `token` | 通过扫码获取的认证令牌。 |
+| `account_id` | (可选) 扫码返回的稳定账号标识，用于保持账号级状态文件路径稳定。 |
 | `allow_from` | (可选) 允许与机器人交互的微信 User ID 列表。如果为空，任何能给此微信号发消息的人都可以触发机器人。 |
 | `proxy` | (可选) HTTP 代理地址（例如 `http://localhost:7890`），适合网络访问受限环境。 |
 
 ## ⚠️ 注意事项
 
-- **单端绑定**: iLink 令牌通常与单个会话绑定。在其他地方重新扫码激活可能会导致旧令牌失效。
+- **一个账号一个 token**: iLink 令牌通常与单个微信账号会话绑定。多个微信账号请作为多个 channel 分别绑定。
 - **频率控制**: 为避免触发微信的风控反垃圾机制，请避免设置死循环触发、高频广播等恶意行为。
