chore(release): v1.28.29 — dashboard edits show up on the way back; one scrollbar again

The third and final layer of the stale-tile bug: saving invalidated the
dashboard snapshot with the default refetchType 'active', but the dashboard
page is unmounted while the user sits in settings — the cell only went stale,
and the snapshot query's deliberate refetchOnMount: false then suppressed the
re-read on same-tab navigation back. The save, reset and ring mutations now
invalidate with refetchType 'all', refreshing the cell mounted or not
(proven live in one SPA session against the real query client).

The sortable settings editors (dashboard layout, medication order, modules,
mood tags x2) painted a second page scrollbar: the sr-only drag hint below
each list is position: absolute, no ancestor was positioned, so it resolved
against the initial containing block, escaped the shell's overflow clipping
and lengthened the DOCUMENT by its static offset. The list wrappers are now
relative; the e2e overscroll guard asserts the one-scroll-floor on these
routes and was negative-tested against the revert.
