[FIX] Replace # anchor links with cross-page paths and route-based legal links in footer

[Siddh2024]

Description

Fixed footer navigation links that used # anchor IDs (e.g., #features) which only work on the landing page. The footer is visible on all customer pages, so these links were broken on any page except /.

Changes Made

• Changed all footer navigation # anchors to /# paths (e.g., /#features) so clicking navigates to the landing page first, then scrolls to the section
• Replaced footer legal links (Features, How It Works, Pricing, Testimonials, About, Contact) with actual route-based legal links:
  • Privacy Policy → /privacy-policy
  • Terms of Service → /terms-of-service
  • Refund Policy → /refund-policy

Testing

1. Open landing page → footer navigation links work as before (scroll to sections)
2. Open restaurant menu page → footer navigation links go to landing page sections
3. Footer legal links navigate to actual route pages
4. No 404s or broken links
