Import improvements

Tracking issue for improvements I'd still like to look at

• import templates #4015 (closed)

Some quick notes that I haven't spun off into issues

• the links from the search go to the import landing page - I think the search kit summary + detailed view (2 links) might be better as an and or an or to that
• when looking at the detailed view the 'import' action only works on rows that are 'validated' - this makes sense in the main import as it doesn't try to import invalid rows but needs some tweaking in that workflow - fixed
• The label for entity_id is not the relevant entity in the search display - tracking progress here https://github.com/civicrm/civicrm-core/pull/25097 fixed
• I tried embedding a SearchDisplay into the summary/progress screen - https://github.com/civicrm/civicrm-core/pull/25087 - I got it working but the flickering was an issue. Closing the PR & tracking here to think about further
