feat: Add public enrollment flow with invitation support

- Created enrollment-flow.yaml blueprint with:
  * Enrollment flow with authentication: none
  * Invitation stage (continues without invitation token)
  * Prompt fields for user registration
  * User write stage with user_creation_mode: always_create
  * User login stage for automatic login after registration
- Fixed blueprint structure (attrs before identifiers)
- Public enrollment available at /if/flow/default-enrollment-flow/
