Previous fix added the content-layer background OUTSIDE the offset
modifier, so the background stayed at the original position and
permanently covered the swipe-reveal area - the yellow trash icon,
75% undo button and 5s countdown were invisible while swiping.
Moved the background INSIDE the offset (background follows the
content): idle = fully covered (no bleed into Sent column), swiping
= yellow trash / undo countdown revealed as before.
Verified: :feature:radar:compileDebugKotlin BUILD SUCCESSFUL.
Not released (batched with pending fixes).
