Bug 37243: Tag moderation actions should be in the last column

This patch updates the tag review template to make the "actions" column
the last one in the table. This makes it consistent with other pages in
Koha.

To test you should have TagsEnabled turned on and at least one
pending tag in the system.

- Go to Tools -> Tags.
- Confirm that the "Approve" and "Reject" buttons are in the last column
  of the table.
- Approve a tag and click the "Approved" link the the "Terms summary"
  box in the right-hand sidebar.
- In this view the table has a "Reviewer" column visible. The buttons
  should still be in the last column.
