Fix
Added compatibility with the new PKMer OAuth Thino device registration flow.
After OAuth login, Thino now reports the current device to PKMer and verifies that the device is active before enabling Pro features.
Improved OAuth failure handling for device-limit, missing-product and missing-scope responses.
修复
兼容新版 PKMer OAuth 的 Thino 设备注册流程。
OAuth 登录后会向 PKMer 上报当前设备，并在启用 Pro 功能前确认当前设备处于可用状态。
优化设备数量超限、未购买产品、scope 不足等 OAuth 错误提示。
