feat(pages): wire v6 sections to all 9 pages

- index.astro: full 9-section home (Hero → Case → Services → Callout →
  Portfolio → Process → Pricing → Faq → Contact prompt form)
- about.astro: v6 Hero + body content from <Content /> wrapped in .fx-prose
- services/index.astro: v6 Hero + v6 Services (4 from collection) + Contact prompt
- portfolio.astro: v6 Hero + v6 Portfolio (pinned 3) + grid of remaining 6 + Contact
- blog/index.astro: PageHero → Hero (badge→eyebrow, subtitle→lede, showStats=false)
- blog/[slug].astro: same PageHero → Hero swap
- faq.astro: same swap (existing bento FAQ body preserved)
- contact.astro: same swap + WIRED form to submitContact() (real backend).
  Was setTimeout 800ms placeholder — now uses contact-submit.ts which
  POSTs to PUBLIC_CONTACT_ENDPOINT (Apps Script) or dev-mocks if empty.
- privacy.astro + terms.astro: same PageHero → Hero swap

Build: 22 pages, 0 errors. Phase 4.9d complete (contact form wired).
