Add UI tests to CI

[mtrezza]

New Feature / Enhancement Checklist

• I am not disclosing a vulnerability.
• I am not just asking a question.
• I have searched through existing issues.

Current Limitation

The lack of UI tests in the CI process makes it difficult to identify bugs before release. That leads to severe bugs likely to make it into release, e.g.:

• Applying filters not working #1991
• Switching apps not working #1994
• File upload in dashboard GUI is not working #2006
• Login fails with req.session.regenerate is not a function #2194

The current manual testing before merging a PR is not reliable nor scalable.

Feature / Enhancement Description

Add UI tests to CI, starting with just a few basic tests as guidance on how to write these tests, that can be extended over time.

Example Use Case
