Created useFormatters() combining useWeightUnit + useCurrency + formatWeight/formatPrice
into a single hook returning weight(grams) and price(cents) bound functions plus
raw unit and currency values. Updated all 14 consumer files to use the new hook,
removing the repeated 4-import + 2-hook-call pattern from each.

Moves CollectionView, PlanningView, and SetupsView out of the 634-line collection/index.tsx into dedicated component files. Pure extraction — zero logic changes.
