Implemented task 1.3 from the development plan. Overridden the `username` field on the custom `User` model to use a `RegexValidator` restricting usernames to alphanumeric characters, underscores, and hyphens (`^[\w-]+$`). This effectively mitigates potential XSS attacks or injection vulnerabilities via the username field. Updated the field's `help_text` to accurately reflect the restrictions. Added full test coverage for valid and invalid username inputs in `users/tests/test_validation.py`. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>
