refactor(ui): move 62 hand-written empty states onto EmptyState

The admin sections, the cycle, illness, medication, mood, records and
settings cards, the pickers and dialogs said nothing-here-yet in a
hand-written muted paragraph in five sizes and three alignments. List
and section states now render through EmptyState (plain, compact; the
three with a next step carry it as the action), and the six chart
bodies through ChartEmptyState at their former height. The thirteen
that stay are a field without a value or a hint inside an editor, not
a list state. The ratchet ceiling drops from 75 to 13.
