chore: add WhatsApp® on first mention across user-facing surfaces

Per Meta's brand-use guidance for third-party products, the registered
trademark symbol (®) should appear on the FIRST mention of "WhatsApp"
on each user-facing page. Subsequent mentions on the same page are
left plain.

Surfaces touched (one-per-page first mention):
- Landing hero badge ("Built on the official WhatsApp® Business API").
- src/lib/seo/site-config.ts: SITE_TAGLINE and SITE_DESCRIPTION
  (rendered into <title> and <meta description> on every page).
- src/app/opengraph-image.tsx: hero text in social-share image.
- Settings, Inbox connection banner, Automations page subtitle.
- README.md tagline.
- All public docs pages (docs/README.md, docs/whatsapp-setup.md,
  docs/getting-started.md, docs/supabase-setup.md,
  docs/environment-variables.md, docs/deployment-hostinger.md,
  docs/automations-and-cron.md, docs/architecture.md,
  docs/troubleshooting.md).

Out of scope: SITE_KEYWORDS (the meta-keywords array isn't
user-rendered text — putting ® on every keyword would look broken in
the meta tag).
