perf/fix: externalize images to WP media; normalize Astra leaks; full-width

Plugin (1.8.2):
- remove all bundled raster images (~9.3MB) from assets/img; hero + single
  hero figure now come from the WP Media Library (Settings), shortcode args
  ([viator_hero image_id]), or the vc_testimonials filter — rendered responsive
- vc_hero_image_source() prefers an attachment ID (srcset); listing/hero use it
- settings: store hero_image_id + single_hero_figure_id (media pickers)
- enqueue at priority 20 + depend on astra-theme-css so our CSS wins ties
- stronger Astra overrides (!important): kill page-builder article top padding
  (gap above hero), force full-bleed containers, guard horizontal scroll
- normalize theme leaks inside .vc-app: no link underline, no list bullets
  (with prose exceptions for the tour Overview); gradient hero fallback

Theme: normalize .hoho link/list leaks; rebuild installable ZIP.
Also: move optimized originals to /removed-images/; ship viator-collector.zip.
