feat(automation): image_edit transform action

A resize of a turned image sends ImageEdit::Transform, which had no
headless path (AGENTS 3). image_edit now takes action transform with
matrix: six numbers in top-left-origin points, like the tool's other
geometry, applied after the image's placement. The tool converts it to
user space through the page's view mapping, and refuses a matrix that is
not finite, is flat (a·d − b·c = 0) or moves the image out of range.
