fix(workflows): make the dashboard pending-approvals card items clickable too

The dedicated Approvals page rows open the underlying document on click, but the
identical card on the admin dashboard didn't — so 'clickable approvals' only half
worked depending on where you looked. Apply the same treatment: the info area is
now a button that navigates to the run entity's detail page (quote -> /admin/quotes/:id,
invoice -> /admin/bills/:id, etc.), reusing the workflows.approvals.openEntity
tooltip. Confirm/Deny stay separate; items with no mappable entity render as plain
text.
