Remove Google OAuth from login/register, enforce email-only authentication

- Remove authType state check from LocalLoginForm (always show registration link)
- Update .env.example files to set AUTH_TYPE=LOCAL as default
- Clarify Google OAuth credentials are only for Gmail/Calendar connectors
- Login and register pages now exclusively use email/password authentication

This change completes the removal of Google OAuth for user authentication while preserving OAuth functionality for Google Calendar and Gmail connector integrations.
