Claude 142df74192 Add AI subject replace: file-picker compositing with LAB color matching
- Backend: POST /api/image/replace-subject
  Uses rembg to extract the subject from a source photo, scales it to fit
  the selection mask bounding box (or canvas centre when no selection is
  active), applies a partial LAB color transfer (blend=0.45) so the
  subject's lighting matches the background, then composites the result.
  Also adds POST /api/image/extract-subject for standalone subject extraction.

- Frontend: "Replace with subject from file" button in the selection panel
  (selection_actions.js) — opens a native file picker so no clipboard API
  or HTTPS is required.  Calls the new endpoint with the current SAM mask.

- Frontend: Image > Replace Subject (AI)... menu entry backed by
  modules/image/replace_subject.js — a full dialog with file picker,
  thumbnail preview, and "match background lighting" toggle.  Works with
  or without a prior Smart Select; if a selection exists it confines the
  subject to that region.
