Standardize the two classify tabs: By-transmittal drops the party→slot→bin
tree (and its multi-field "+ Transmittal" form) for a flat per-file grid that
mirrors By-tracking. Each file gets ONE editable text input — its full
transmittal folder path "<party>/<received|issued>/<YYYY-MM-DD_TN (STATUS) -
Title>". Committing it find-or-creates the party/slot/bin; structure stays
derived, never stored.
Drag-and-drop (from the source tree onto the grid):
- plain drop on a routed row → the dropped files JOIN that row's folder;
- ⌘/Ctrl-drop on a routed row → a prompt prefilled with that folder's path
lets you edit it into a NEW transmittal the files go to (the original is
untouched; an unedited path dedups via find-or-create);
- drop on empty space / an unrouted row → files are added as blank rows to fill.
Model (classify.js): adds a `transmittalWorkset` (parallel to trackingWorkset)
plus addToTransmittalGrid / removeFromTransmittalGrid / transmittalGridKeys and
setTransmittalPath(keys, path) — the single parser for "<party>/<slot>/<folder>"
that also prunes any bin a re-route empties. app.js importPaths now reuses
setTransmittalPath for its route axis (one parser, less duplication).
Removes the now-dead tree rendering/CRUD (party/bin nodes, binForm, the bin
filename editor, the bin drop zone). Tests updated to the grid model: tab
render shows the folder-path input; drop join/branch/empty; edit re-routes and
prunes the emptied folder; ✕ removes. 71/71 classify specs pass.
