Add password login support to web UI and backend

Implement password-based QQ login across the stack: add a PasswordLogin React component, integrate it into the QQ login page, and add a frontend controller method to call a new /QQLogin/PasswordLogin API. On the backend, add QQPasswordLoginHandler, router entry, and WebUiDataRuntime hooks (setPasswordLoginCall / requestPasswordLogin) plus a default handler. Register a password login callback in the shell (base.ts) that calls the kernel login service, handles common error cases and falls back to QR code when needed. Update types to include onPasswordLoginRequested and adjust NodeIKernelLoginService method signatures (including passwordLogin return type changed to Promise<QuickLoginResult>) and minor formatting fixes.
