Header gets a Rename / Classify & Copy switch. In Classify & Copy mode the
spreadsheet pane is replaced by a tabbed target pane (By tracking number /
By transmittal), while the source tree stays on the left.
- target-tree.js: renders both trees from classify state; tracking-folder
create/rename/delete (leaf folders styled as the revision); party CRUD +
per-slot inline transmittal-bin form (date + TRN/SUB + seq + optional
status/title); shows the derived filename + a validation badge for each
placed file; live header stats (done / in progress / unassigned / excluded).
- app.js setMode(): swaps panes, toggles classify mode, re-renders both trees.
- 3 UI smoke tests added to classify.spec.js (12 total green).
