refactor(medications): collapse detail-page chrome to one heading scale

Lift the section-header chrome on /medications/[id] to one canonical
shape so the page reads as one document. Every section header now uses
text-base font-semibold leading-6 tracking-tight via the shared
<MedicationDetailSection> primitive (which keeps the surrounding
border-border/60 + px-3 py-2.5 + border-t contract). DrugLevelChart's
standalone header migrates to <h2> with the same classes.

Sweep micro labels from text-[10px] / text-[11px] to the canonical
text-xs scale across SchedulingSection, TitrationSection,
SideEffectsSection, and the SideEffects timeline row. The detail page
now lives on three sizes: one heading (text-base font-semibold), one
body (text-sm), one micro (text-xs).

Closes FB-F3 and FB-F4. Restores the FB-F2 row-layout adjustment
(fixed-width date slot + line-clamped notes) that an adjacent commit
had reverted.
