KenM76andClaude Opus 5.5 e93e8d50ba fix(edit): keep a soft mask anchored when the edit is lifted over the scan (#3973) ...

A soft mask is placed by the CTM in force when its `gs` runs (ISO 32000-2
11.6.5.2). The paragraph lifted over the scan re-selects the graphics state
after its own `cm`, so a mask selected before a translation landed
translated with it and could hide the new text. A re-emitted state that
carries a dictionary /SMask now records its anchor CTM and is selected
there: `cm` to the anchor, `gs`, `cm` back.

The test edits the same paragraph with and without a mask and requires the
same ink; it fails with the re-anchoring disabled (the mask lands 100 pt
right and the text vanishes). Both rewrite paths.
