Enhance login process to support team selection and improve token handling

- Added ScopeTeamSelection constant for temporary access token.
- Updated LoginByUserID function to include team selection logic based on user team count.
- Modified access token generation to use user subject for both MFA and team selection scenarios.
- Enhanced LoginResponse structure to include TokenType and Scope fields for clarity.
