fix: download before uninstall and point prod installer to stable update URL

Swap uninstall/download order in reinstall path so a failed download
doesn't leave the user with nothing installed. Rename downloadAndInstall
to downloadAndVerifyDeps to reflect what the function actually does.
Update prod installer URL to update-latest-stable-prod.json.
