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

Browse Source 
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).

// Makes a modal dialog draggable by its header, Photoshop-style.
//
// On the first grab the dialog is switched to `position:fixed` anchored at
// its current on-screen box, so it follows the pointer independently of the
// host modal's centering/transform layout. Dragging is clamped to the
// viewport and ignores presses that start on interactive controls (buttons,
// inputs, selects) so clicking Cancel/Create never becomes a drag.
