fix(desktop): count only active MaterialLedger holds and link the nest page

MaterialLedger's Release lets a hold go, so a Released hold no longer keeps
a sheet for the nest; only Proposed, Approved and AwaitingCloseout holds,
the statuses ML counts against free stock, are open. The Has Been Cut
note's link pointed at /Nests/{id}, which ML does not serve; its nest page
is /Nests/Details/{id}.
