Phase 4: pricing, about, area, Windows 10 and business pages

- /pricing: full price list, no-fix-no-fee terms, travel and payments
- /about: first-person page from confirmed facts, links to area pages
- /areas/[suburb]: Te Atatū Peninsula, Te Atatū South, Henderson and
  Massey, generated from src/lib/areas.js with suburb-specific copy
- /windows-10: options page with free Windows 11 check; October 2028
  used for business Extended Security Updates
- /business: $65/month plan (2 hours, no lock-in, no rollover)
- Nav gains Pricing/About and Business/Windows 10 links; footer rebuilt
  with address, hours and links; homepage links areas, /business and
  a Windows 10 banner; sitemap includes all new routes
- Mobile menu hides by its own height (fixes overflow with more links);
  hamburger now used below 900px so the link row never overlaps
