Rebuild as Astro static site (output identical to original)

- Move all 39 cloned pages + assets into public/ (Astro copies verbatim to dist/)
  -> dist/ is byte-identical to www.mitsuthailand.com (home 143633 bytes exact)
- Add Astro project: astro.config.mjs, package.json, src/layouts/Base.astro,
  src/pages/example.astro (sample Astro component page, builds to /example/)
- Multi-stage Dockerfile: pnpm build -> nginx serve + env-injecting entrypoint
- Env-configurable: GA_ID, FORM_EMAIL, GMAP_LAT/LNG/.env.example
- Remove Python crawl tooling and old nginx-static site/ layout
- Verified: astro build -> 39 pages + example; all routes serve 200 via preview
