Bug 30577: Move item specific pickup locations to the left

Bug 30577: Move item specific pickup locations to the left

When placing holds, staff will set the pickup location at the top,
choose an item, then place the hold.
It is easy not to notice the item specific locations dropdown.

This patch moves it in line with the other selction areas on the request screen.

To test:
 1 - Find a record on staff client, place hold
 2 - Select a patron to load the request screen
 3 - Note the location dropdown for next available hold
 4 - Note the item specific locations on the far right
 5 - Apply patch
 6 - Reload the page
 7 - Note the item specific location dropdowns are now moved to the left
 8 - Place the hold, verify it works with the dropdowns
 9 - Verify title levelholds still work as expected
10 - Verify multi-holds still work
