fix(deploy): production site URL, legacy URL redirects, sitemap, PR build check

- astro.config.mjs: site was still iptf.netlify.app — canonical/OG URLs
  now point to iptf.ethereum.org
- Add permanent redirects for all 13 legacy Jekyll post URLs
  (/:title/ from filename) to their new title-derived /blog/<slug>/ routes
- Add @astrojs/sitemap (replaces jekyll-sitemap) and point robots.txt
  at sitemap-index.xml
- deploy.yml: run the build job on pull_request (validate without
  deploying) so deploy breakage is caught before merge
