chore(mobile): don't show drag scroll date in search page (#17594)

Dont show drag scroll date in search page

* When using the drag scroll, the date of the current image is shown. This is now made toggleable.
* For the mobile search result page, the display of the date is now disabled because the results are not sorted by date and therefore a display of the date is not desirable.
