Show when a video was last queued on search results

When a video is searched for, the result should in some way indicate when that video was last queued.

Start by locating the JavaScript code that renders search results and trace whether each video already exposes a last-queued time. Clarify the intended display and identify the data source for that timestamp; done means search results visibly show when each video was last queued and the relevant behavior is covered by the project's existing checks.
