feat: switch to markdown content collections + remove emdash integration

- Remove emdash from astro.config.mjs (no more SSR/runtime)
- Remove emdash + @astrojs/node from package.json
- Switch output from 'server' to 'static'
- Rewrite src/content.config.ts with 6 collections:
  pages, services, portfolio, faq, settings, blog
- Keep live.config.ts as inert stub for build compat
- Push new content from content-temp/pages/ into src/content/pages/
  with full schema (title, subtitle, badge, hero_image, show_cta, cta_*, etc.)

Build: 18 static pages, 0 errors
