feat(photo-editor): Ajax Image Editor client (Photoshop-parity tools)

Photoshop-parity editor client: layers, selection/masking, brushes,
smart filters, LUT import, Quick Edit, mobile gestures, workspaces,
batch operations, and the service-worker versioning (v978->v1006).

Source: vendor/photocraft (ad1cff44) photo-editor client files, merged
onto upstream/dev (a8c147b2). Conflict resolution documented in
pr_work/A_conflicts.md; editor files taken from vendor/photocraft
(upstream's editor is an earlier snapshot of the same feature).

+"""The Window dropdown toggles panels and dots the ones currently shown.
+
+Every row is a real toggle (click = show/hide), the menu stays open while
+clicking, and a dot marks the panels/dialog/workspace that are active. The
+dot state is computed by the composer (galleryEditor.js) and handed to
+wire-extra-menus as `syncWindowChecks` + `togglePanel`, so that file owns
+no state.
