fix(ui): mobile stacked intake history, icon-collapse bulk bar, ResponsiveSheet parity, tap-target floor

Intake history stayed a 4-5 column table with two full datetime columns
on mobile, forcing sideways scroll of a primary history surface; add
the stacked card-list split below md (the measurement-list pattern) and
lift the row kebab off a hard 32px box onto the size-11/size-9 floor.

The documents bulk-action bar wrapped five labelled buttons into a
2-3 row floating slab at 360px; collapse to icon-only (aria-label
carries the name) below sm, matching the document-detail-sheet
footer's established pattern.

Two coach/medication modals were still on raw Dialog while every
sibling had moved to ResponsiveSheet: the schedule-era editor and the
document attachment picker. Both now share the bottom-sheet-on-mobile
primitive; the era editor's submit button associates to its form via
the native `form` attribute since the footer slot sits outside the
form's DOM subtree (the log-intake-dialog precedent).

Tap-target floor: side-effect entry chips and the coach attachment-pill
remove control were below the 44px floor; the chips get a min-h-11
flex-center, the pill remove gets an invisible hit-slop instead of
growing the pill's visual footprint. Two insights empty-state CTAs
were missing the existing `ctaSize="lg"` treatment already used by
their sibling empty states.
