feat(auth): enhance email validation when no workspace available + disable captcha on email validation (#11239)

Implemented fallback logic to associate a user with a workspace when
none is found. Introduced new GraphQL types and mutations for roles and
permissions management. Simplified and refactored URL-building logic for
email verification, improving code maintainability and flexibility.
