cproudlock 036090348c imaging: persist tile expanded state across page refresh ...

localStorage-backed set of serials at key 'imaging-expanded'. On
DOMContentLoaded, walk each .imaging-card; if its data-serial is in
the set, set card.open=true. On every <details> toggle, update the
set. Refresh no longer collapses the tile the operator was looking
at.

Per-browser state (localStorage), no server round-trip.
