fix(plating): tree editor — expand newly imported nodes + Expand/Collapse All

Two related gaps:

1. loadTree() only auto-expanded nodes when expandedNodes was
   completely empty — that was "first-load only" behaviour. After
   an import, the subsequent loadTree() found the map populated
   and skipped the expand pass entirely, so every freshly imported
   node came in collapsed ("2 hidden"). Users had to click each
   one open by hand.

   Fix: iterate the whole tree on every load and default any node
   whose id isn't yet in expandedNodes to true. Nodes the user
   explicitly collapsed stay that way (their id IS in the map,
   set to false).

2. Added "Expand all" and "Collapse all" buttons to the tree-
   editor header so operators can get a full view (or a tight
   overview) without clicking node by node. Collapse all keeps
   the recipe root expanded — otherwise the canvas goes blank.
