fix(documents): bump timeline control buttons to 44x44 (#385)

Browse Source 
WCAG 2.5.8 (target size, AA) requires 44×44 minimum, and the
project's senior persona makes that a hard floor on desktop too.
Reset-zoom: h-6 → h-11 + min-w-[44px] + px-3.
Clear-selection: h-6 w-6 → h-11 w-11.

Two regression tests on the TimelineDensityFilter spec assert the
sized classes so a future shrink can't slip through silently.
