fix(medications): rebase dashboard compliance denominator onto the schedule

The dashboard compliance tile set scheduled = COUNT(*) of logged intake
rows, so its rate (taken / scheduled) sat at ~100% across every window
regardless of real adherence — every logged row was both numerator and
denominator, and the 7/30/90 windows never diverged.

Anchor scheduled to the canonical recurrence engine's expected-dose count
per day, summed across active medications, so days the schedule expected a
dose the user missed pull the rate down and the windows genuinely diverge
with partial adherence. taken is capped per day at the expected count so a
duplicate log can't push a day above 100%. The response shape stays
{date, scheduled, taken} for the existing chart consumer.

Regenerate the OpenAPI contract for the new expected/missed count fields.
