Show each dimension's parameter name while creating or editing it, and let
users insert another driving dimension at the expression cursor or selection.
Use the available editor width and keep Apply aligned with the right edge.
Add a tools dropdown with Measure, named user parameter expressions, and
access to the existing parameter table for adding and editing parameters.
Preserve the unfinished dimension expression while either window is open.
Cover reference insertion, dependent updates, parameter selection, dialog
round trips, applying and cancellation with UI integration tests. Update the
parameter guide.
