feat: Instagram data sync, gold accent, SVG logo, FAQ & Pricing sections

- Sync all content from Instagram: fix addresses, trainer names, add 5 new
  trainers, remove 2 inactive, update class descriptions
- Add FAQ section (11 Q&A items) and Pricing section (tabs: subscriptions,
  rental, rules)
- Redesign with editorial magazine feel: centered headings, generous spacing,
  section glow effects, glassmorphism cards
- Migrate entire accent palette from rose to warm gold (#c9a96e)
- Replace low-res PNG logo with vector SVG traced via potrace — crisp at any
  size, animated gradient (black↔gold), heartbeat pulse animation
- Make header brand name gold
