Fix: Settings page now correctly navigates to Dashboard after saving Schwab credentials
Problem: On macOS and Linux, after entering Schwab API credentials (AppKey, AppSecret, AccountNumber) on the Settings page and completing the OAuth login flow, the application would return to the Settings page instead of proceeding to the Dashboard. This prevented users from completing the initial setup and accessing the trading dashboard.
Resolution: The post-authentication flow now properly directs users to the Dashboard after saving credentials and completing Schwab authorization. The end-to-end workflow — Settings → Schwab authorization → Dashboard — is now seamless on all platforms.
