`includes('mui.com')` matches any host containing `mui.com` as a
substring. Switch to an exact-or-subdomain check so the service worker
only registers on the real mui.com deployment.

Summary
Closes CodeQL alert "Incomplete URL substring sanitization" on
serviceWorker.ts.window.location.host.includes('mui.com')matches any host wheremui.comappears anywhere in the string. Switch to an exact-or-subdomain check so the service worker only registers on the real mui.com deployment.Two-character semantic improvement; not a meaningful attack vector since
window.location.hostis browser-provided, but the new code is more correct.
