🐛 User denial status does not update in database

# 🐛 Summary #

When a region admin denies access to a user, the user is not being removed, or marked as "Denied" in the database. This behavior is inconsistent with the intended functionality.

## To reproduce ##

1. Login as a Regional Admin
2. Access the Regional Admin Dashboard
3. Deny a Pending User request
4. Review database that any record of that User account has been removed or marked as "Denied".

## Expected behavior ##

- User Removal/Marked on Denial: When a region admin denies access for a user, the user’s record must be removed from the database as an active User. Verify that the user’s data is no longer accessible as an active account.
- Database Consistency: Ensure that the database remains consistent by invoking a denied user.
- Testing and Validation: Conduct automated tests scenarios where region admins deny access for users. Confirm that the denied users are addressed appropriately in the database.
