fix(storefront): replace hardcoded strings with i18n, neutral empty-state wording

- Route aria-label/alt/title strings (rating, discount, carousel arrows,
  hero slides, dialog close, toast dismiss, QR code, bank payment iframe,
  guest checkout fallback) through the translate pipe/service instead of
  literal English.
- Drop the "Oops!"/"Упс!" apology framing from category/subcategory empty
  states (en/ru/hy) - zero results is not an error.
