frontend: center wallet-sync stepper and record-history timeline

Replace the bespoke left-aligned DialogStepper with the Origin UI Stepper
primitive (components/ui/stepper.tsx) so the numbered indicators sit centered
inline with their labels. Rebuild the patient sheet's Record History section as
a vertical Timeline (components/ui/timeline.tsx) showing the actor name, an
entity-type icon, the action, and the date, replacing the flat avatar list.
