CATEGORY_LABELS was built at parse time before translations were
available, causing raw keys like 'categories.verdura' to appear
in all category labels, dropdowns and inventory filters.
_applyI18nToLabels() now also:
- Rebuilds each CATEGORY_LABELS entry using the loaded i18n strings
and the corresponding CATEGORY_ICONS icon prefix
- Regenerates the static #pf-category <select> options so the
product-add form also shows translated category names
