Add a filter for non-zero findings in OpenScanHub dashboard

[siteshwar]

Description

OpenScanHub dashboard should have a filter for non-zero findings to make it easier to find packages that may be introducing new bugs. Currently, it displays large amount of tasks with zero findings.

Benefit

It would make it easier for Packit and OpenScanHub developers to manually monitor tasks and report findings upstream until it is done automatically.

Importance

Currently maintainers may be ignoring findings that may be introducing real bugs in the code.

Workaround

• There is an existing workaround that can be used until this feature is implemented.

Participation

• I am willing to submit a pull request for this issue. (Packit team is happy to help!)

Currently the dashboard is heavily limited by current general API structure. I have a few issues opened over on the packit-service front to improve this, but the specific issue I'd say is the most important is moving to FastAPI or generally restructuring the View-Model situation -- both of which would take some time but would mean adding filtering, searching, and ordering would be a piece of cake.

• Move from Flask to FastAPI for the API packit-service#2567
• https://github.com/packit/packit-service/issues?q=sort%3Aupdated-desc+is%3Aissue+is%3Aopen+author%3AVenefilyn

In short, not much we can do on the dashboard front that wouldn't be extremely API heavy or generally ugly with client-side filtering.
