chore: sync local working copy as of 2026-08-15

The Gitea repo was initialised from an earlier snapshot, so main and the
machine this runs on had drifted apart in 153 files before any UI work
started. This commit brings the branch up to the local tree as it stood
on 2026-08-15 21:31 (from cowork_local.7z), so the redesign that follows
shows up as its own reviewable diff instead of being mixed in with the
pre-existing divergence.
