fix(a11y): increase all PdfControls buttons to 44×44px touch targets

Browse Source 
Add min-h-[44px] min-w-[44px] to all five PDF viewer buttons (prev,
next, zoom in, zoom out, annotation toggle) and widen icon-only
padding from p-1 to p-2. Adds aria-pressed to the annotation toggle
for correct toggle semantics (WCAG 2.2 §2.5.8 + ARIA 1.2).
