feat(medications): wire the Verlauf tab onto the dose-history ledger

Replace the Verlauf tab's flat intake table with the per-slot dose-history
ledger the shared band engine mints. The tab now renders EVERY expected slot
with its status — on-time, late, skipped, missed, upcoming — even when the
dose was never taken, and tags every off-schedule intake as a standalone
ad-hoc row at its real time. Rows group by day, most-recent first.

Genommen / Übersprungen sit on the dose row and recompute instantly: the
cached ledger and the headline adherence are mutated optimistically (the
engines are pure, so the client mirrors their accounting) before the write
fires, then the dependent-key invalidation reconciles; a failed write rolls
the optimistic snapshot back. A header add dialog records a dose — including a
backdated or off-schedule one — and an off-window take surfaces the "diesem
Slot zuordnen?" nudge, pinning it onto a chosen slot via forceSlotInstant
rather than orphaning it. A compact took/skipped bar sits at the top of the
tab; the card body still never tints by status.

Adherence is derived from the same ledger the user is reading (taken over
taken + missed; skip, ad-hoc, upcoming excluded), so the history view and the
percentage cannot contradict. New status + dialog copy in all six locales.
