fix: Astra style conflicts, full-width, responsive hero images, header search

Plugin (viator-collector 1.8.1):
- is_vc_page() now matches any Viator shortcode, so shortcode Pages (home)
  get the full-width no-sidebar canvas
- load vc-design.css after Astra + inline overrides: strip Astra page-builder
  article padding (removes extra gap above hero), full-bleed containers,
  enforce design font inside .vc-app
- vc_hero_img_html(): render hero from the WP media library with responsive
  srcset when the image is an attachment; used in listing + [viator_hero]
  ([viator_hero image_id=".."])

Theme (astra child):
- remove the user/profile header item
- working header search (expands, submits to the tours archive ?vc_q=)
- load chrome.css after Astra + enforce design font inside .hoho
- rebuild installable ZIP
