Inconsistent Validation Rules Between Admin UI and Web Server for User Creation

[RobertKeyser]

Bug Description

When creating a new user and you try to add a space, the Admin UI allows you to submit the request to the web server, receives a 422 stating that spaces are not allowed in the username; however, it then never displays an error message or toast indicating that it was unsuccessful.

Steps to Reproduce

• Open the network tab of your browser's
• Try to create a new user in the admin UI with a valid password but the username bad user
• Click save
• Receive a 422 from the API call
• No feedback in the admin ui that the request was unsuccessful.

Expected behavior

A few things:

• The front end should validate that the username conforms to Fides's expectations.
  • If the user inputs an invalid username, they field should be marked as invalid and the save button should be disabled
• The error from the backend was not displayed to the user via a toast or other error message. This leaves the user in an indeterminate state, not knowing whether their action was successful or why it was unsuccessful.

Environment

• Version: Tested on 2.14+
• OS:
• Python Version:
• Docker Version:
