feat: tour page photos-first layout, mobile booking bar; board 1 fixes

Tour page (boards 2 and 3):
- Replace the blurred 'Welcome to {city}' hero with a breadcrumb and a photo
  gallery (1 large + 2, 'All N photos' opens the lightbox); the H1 title,
  rating with review count and facts follow; booking card stays sticky
- Phones/tablets: swipeable photos, name before price, 2x2 facts, and a
  fixed bottom bar with price + Check availability (vc-tour.css)

Board 1:
- Hide Viator internal tags ('Agent Low Quality Product'...) from the tour
  category, listing filter and activities section (VC_Tags, tested)
- Listings: run the query filter late and set posts_per_archive_page so
  pages show 12 tours as the count says
- Footer columns without a menu show default links (quick links, structure
  cities, contact/about/faq) instead of empty headings

Plugin 1.9.5, theme 1.0.13.
