feat(meds): simplify the detail page into the history view

The detail page carried an Edit / History / Advanced action row and a
'Rhythmus' cadence block that duplicated the card actions. Drop them:
editing and advanced settings are now reached from the card overflow
menu only. The detail page leads with the intake-history table, keeps
the GLP-1 drug-level / titration as a default-closed disclosure, and
renders a compact, read-only summary header (name, dose, status, plain-
language cadence line).

+/**
+ * v1.7.2 W3 — compact, non-editable medication-detail header.
+ *
+ * Supersedes the v1.7.0 `<MedicationDetailHeader>` (Edit / History /
+ * Advanced action row) and the `<CadenceSummaryRow>` "Rhythmus" block.
+ * The detail page is now history-centric: editing and advanced settings
+ * are reached from the medications-list card kebab only, so this header
+ * carries NO action buttons. It is a read-only summary line:
+ *
+ *   name (H1) → dose (muted) → status pill → plain-language cadence line
+ *
+ * One-shot medications render `Einmalig am …` in place of the cadence
+ * summary; a pending one-shot falls back to the pending copy.
