Order the row actions by what they do to the row

[JeroenDeDauw]

Follows-up to #1356

The Data tab's row actions ran Promote, Edit, Copy link, Move, Delete, then the drag handle.
Copy link, which changes nothing, sat between actions that do; the rarely used Promote led the
strip where the most used action, Edit, belongs; and the handle, which is grabbed rather than
clicked, followed Delete with nothing between them.

The strip now runs Copy link, Edit, Promote, Move, Delete: the one action that leaves the row
as it is first, then the two that change it in place, then the two that take it out of the
listing, with Delete last. The main row keeps its pin as the indicator beside the title. The
overflow menu follows the same order, and the drag handle stands a little apart from the buttons.

Considered, omitted: moving the drag handle to the row's left edge, the wider list convention,
which would put it beside the expand chevron and the main row's pin.
