refactor: Simplify OAuth authentication flow and update branding

- Remove complex OAuth parameter handling in UserAuthorize component
- Streamline sign-in process with direct dashboard redirect
- Update UserAuthForm to use simplified branding (Q58 instead of Q58论坛)
- Add session update after successful authentication
