feat(medications): collapsible advanced groups + injection titration timeline

Restructure the medication detail advanced surface (Erweitert + API tabs)
into expand/collapse groups: SettingsGroup gains an opt-in collapsible
mode built on the same Radix Collapsible primitive SheetSection uses, so a
long settings wall reads as scannable sections. Lifecycle and external-API
groups default open; Data and the destructive zone default collapsed.

Add a titration timeline to the injection tab — completed and planned
dose-escalation steps rendered as a vertical timeline with a "you are
here" marker. Reads the existing MedicationDoseChange stream (future-dated
rows are planned steps), so no schema change is needed. Neutral palette,
no state-driven colour.
