This pull request enhances the test progress experience during regression test execution.
Previously, the “Testing” stage provided no real-time indication of progress, which could feel unresponsive for users running multiple test samples.

1. Added a dynamic progress indicator that visually updates as each test completes.
2. Modified the by_id.html template to include a JavaScript polling function.
3. Integrated progress updates using the existing /tests/<test_id>/progress route.

Have you run this yourself to verify in any way that this is actually working?

Hi @canihavesomecoffee

Thanks for the review.
I started the app locally (python run.py) and manually verified the progress bar UI (simulated a running test to see the AJAX updates). That part was successfully tested.
But, I haven't run the full test suite across all CI Python versions or addressed the SonarCloud findings.

I’d like to fix these issues ASAP. Could you please guide me ahead ...
