feat(invitation-signup): optimize user registration process and enhance localization

- Introduced a new SQL migration to optimize the invitation signup process, allowing invited users to skip organization and team creation.
- Updated the `register_user` and `register_google_user` functions to handle invitation signups effectively.
- Enhanced the `deserialize_user` function to include an `invitation_accepted` flag.
- Added new localization keys for creating organizations and related messages in multiple languages, improving user experience across the application.
- Updated the SwitchTeamButton component to support organization creation and improved styling for better usability.
