fix: serve downloads only on the site host and select the clicked Quest build

Review follow-ups:
- The downloads routes now answer only on the apex (the site's host) and 404
  on every other accepted host, so the game's open API/CDN subdomains can't
  serve the builds.
- Install on Quest passes its own file to the Quest page instead of always
  picking the newest release.
- Waiting for the bucket's headers is limited to 30 s; the body still streams
  without a limit.
- Dispose the upstream request message; use LINQ in FindFile.
