chore(medications): remove unused IntakeTimeline component

The component was exported but never imported anywhere — only the file
itself contained the three references (the props interface, the
function declaration, and the type annotation). Likely an early scaffold
for the v1.4 medication-intake redesign that was superseded by the
intake-card layout before any caller wired it in.

No tests existed for this component, so the delete is single-file.
