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).

+"""Static contract tests for the View > Panels visibility feature.
+
+The panel-visibility module, its CSS, the View/Window menu markup, the wiring
+and the control-op catalog are plain JavaScript, so these tests assert the
+contract at the source level (the project's editor suites are contract/static,
+not a JS runtime).
