feat: 添加授权码管理和设备自注册功能

- 新增 `AndroidTenantProviderConfig` 配置类，提供租户解析逻辑
- 更新 `AndroidAuthService` 接口，添加 `authenticateHttp` 方法的可选参数
- 新增前端授权码管理页面 `LicenseManagement`，支持授权码列表展示和导入
- 新增 `AndroidDeviceRegistrationServiceImpl` 的 `register` 方法，支持设备自注册并验证租户代码
- 更新 `AndroidAuthServiceImpl`，在认证过程中应用授权信息
- 更新相关 DTO 和接口，支持新的授权和设备注册逻辑
