feat(meezi_app): café profile parity — cover, open badge, gallery, hours (code-only)

Enhances the café detail screen toward web-Koja parity. Parsing verified against
the real backend DTOs (CafePublicDto / WorkingHoursPublicDto), still unbuilt (pub blocked).

- Cover image hero (coverImageUrl), open/closed badge (isOpenNow).
- Photo gallery (galleryUrls) horizontal strip.
- Working hours rendered from the day-keyed WorkingHoursPublicDto ({sat..fri} of
  {isOpen,open,close}), Sat→Fri with Persian day labels.
