fix(mobile): raise primary touch controls to the 44px floor

Sweep the primary touch controls that sat below the 44px tap-target
floor on phones onto the canonical `min-h-11 sm:min-h-9` (text) /
`size-11 sm:size-9` (icon) pattern, condensing back at `sm:` upward:

- Coach composer mic / stop / send icon buttons (were `size-9`).
- Dashboard hero CTA, link and action variants (were `size="sm"`).
- Vorsorge list-view "mark done" button (was `min-h-9`) and its kebab,
  which now uses `size="icon-lg"` so the rendered control is 44px
  rather than the icon variant's 40px.
- Illness list-view "log day" button (was `min-h-9`).
- Medication wizard Step 3 injection-sites disclosure (was `h-9`).

The Vorsorge dashboard-card capture action was raised alongside the
ListRow migration.
