Two fixes on the medication cards.
Next-due: the card recomputed "next intake" client-side from
`daysOfWeek` + `windowStart` alone, ignoring rolling intervals, RRULE,
one-shot doses, and the last-intake anchor. A rolling medication (e.g. a
35-day interval) showed "tomorrow" and never re-anchored after a dose.
`GET /api/medications` already returns `nextDueAt` per medication,
computed by the canonical recurrence engine anchored on the last intake.
Both card variants now render that value directly: the generic card
drops its `getNextOccurrenceTimestamp` walker, and the GLP-1 card drops
its weekly-only predictor that hardcoded a 7-day step. The day-label and
window-range rendering are unchanged; only the timestamp source moves to
the server. `nextDueAt` is threaded through the list page's medication
type into both cards.
Intake confirmation: tapping Taken / Skipped now raises a toast naming
the medication ("… recorded as taken" / "… skipped"), so the action has
clear feedback. The next-intake line refreshes on the invalidated list
query, which the next-due fix above makes accurate.
