Merge branch 'qf-scroll-layout' into bottom-strip-shell

Mounts a 24px strip at the bottom of the app under the same gate as the side
nav, behind the SAVED_VIEW_ENABLED localStorage flag shared with saved views.
Shows the build version on the left for now; the per-page left slot and the
right side actions come in later tickets.

To give the strip a stable box, `.app-content` becomes a column flex and
`LayoutContent` takes the height left over instead of `height: 100%`. Fixed
bottom elements read `--bottom-strip-height`, which only exists while the strip
is mounted, so with the flag off every offset falls back to where it is today.

Hides nothing. Each later ticket hides the piece it replaces.
