Give every empty list one empty state and one add action

EmptyState now has a single action shape: centred at its own width on
the 44 px tap floor, never stretched edge to edge on some pages and
compact on others; the per-call-site size switch is gone, and the
dashed card takes the card radius. While a list is empty its empty
state carries the add action, so the header drops its own add button
there (measurements, mood, medications, labs, vaccinations, documents,
illness, check-ups, visits, procedures). The dashboard medication tile
of an account without medications offers 'Add a medication' instead of
'no data in the chosen range'.
