fix(medications): the cards hold one shape and the list refetches on return

The low-supply notice moves onto the adherence meta row beside the streak —
a slot every card already reserves in every state — so a card that is low
on stock no longer inserts a row that pushes its bars out of line with the
card beside it. The gap between the drug class and the first line tightens
at the same time.

The medications list, compliance summary and supply reads now refetch on
every mount. App Router unmounts the page on navigation away and remounts
it on return; inside the client staleTime that return served a cache that
could be minutes old, hiding a dose logged on another device or surface. A
Playwright spec guards the return-navigation refetch.
