feat: comprehensive light theme support across entire site

- CSS foundation: theme-aware scrollbars, section glows, glass cards with
  gold shadows, stronger animated borders and glow effects for light mode
- Hero: consistent dark-video treatment for both themes, brighter gold
  gradient text, glowing CTA button
- Gradient text: auto-switch to warm gold tones on light backgrounds via
  html:not(.dark) selector
- Team profile: inverted ambient photo bg with white overlay for light,
  dark text/borders, gold-dark labels for contrast
- All sections: text-neutral-500→600 upgrades for WCAG AA contrast,
  gold shadow accents on cards (About, Pricing, FAQ, DayCard, News)
- Admin: replaced hardcoded #c9a96e with theme tokens, fixed select
  options, array editor borders, booking badges contrast
- Header: white text on transparent hero, dark text after scroll
- UI components: BackToTop, FloatingHearts, ShowcaseLayout tabs,
  SignupModal, NewsModal, GroupCard adapted for light backgrounds
- Updated CLAUDE.md to reflect dual theme support
