500 Internal Server Error on Organization Signup

[danielsjoo]

The server was throwing an ArrayIndexOutOfBoundsException in OrgEnrollmentStatus.java despite the frontend payload looking ok. (could be a front end issue, will investigate)

Cause: The error handling logic expects status messages to follow the format "STATUS_NAME: Description" so it can split the string by : to extract the description.
Issue: Several enum values, including FAIL_TO_CREATE, FIELD_EMPTY, and INVALID_CHARACTERS, were missing this prefix (e.g., just defined as "Could not create user...").
