fix(web): drop retired /docs, /roadmap and /changelog from sitemap lastmod generator

The generator still listed the removed docs sections, roadmap and changelog
(all moved to docs.autopilotmonitor.com / retired), and lacked /get-started,
which the sitemap emits -- so that entry got "now" as lastmod on every build.

- PAGE_MAP now matches exactly the URLs app/sitemap.ts emits
- generator fails on a missing source file instead of using the deleted
  file's last commit date
- sitemap throws at build time for a URL without a lastmod entry
- fix stale comment: the /docs redirects live in staticwebapp.config.json
