Refs #15727 -- Updated AdminSeleniumTestCase to use ContentSecurityPolicyMiddleware.

Replaced the custom CSP middleware previously used in the admin's
AdminSeleniumTestCase with the official ContentSecurityPolicyMiddleware.
This change ensures alignment with Django's built-in CSP support.

Also updates the test logic to inspect browser console logs to assert
that no CSP violations are triggered during Selenium admin tests.
