Missing language update and a broken test (should be an easy one to fix).

Can be QA'd already

What works:

Love this feature!! Sorting works, also when a filter is applied (e.g. only Medium and Low findings). Searching makes this page so much better.

What doesn't work:

Only improvement I can think of is that the explanation text of the search bar should be updated, as "Object ID contains" is not that user friendly. Maybe we could update the explanation text to something like: "Search for (partial) findings, hosts or IP-addresses. The search functionality is case sensitive. "

Bug or feature?:

After closure of [#3494 ] and reviewing the demo screens, it seems we lack the requested columns (10-okt) in the closed ticket:

"Kennisnet would like to have the ability to see when an object was created and last verified. If we could sort by this information, it would create a sort of journal that tracks objects added over time. This feature would be incredibly helpful, as it allows you to quickly see which items have been added since the last time you checked. This functionality should be available on both the findings page and the objects page, and it would also be great to have a search option for objects on these pages."

Is there a possibility to have this function added to the design?
