Fix race condition: defer license fetch until Firebase auth is ready

[Copilot]

On a cold browser load (incognito, direct URL), clicking "See License Details" before Firebase's onIdTokenChanged has fired causes getUserAccessToken() to throw "Cannot retrieve access token" — currentUser is still null at that point.

Changes

• LicenseDialog.tsx
  • Consume isAuthReady from the existing useAuthSession() context
  • Gate the loadingLicense dispatch on isAuthReady, so the fetch is deferred until Firebase has a resolved user (anonymous or authenticated)
  • Show CircularProgress while waiting for auth to initialize, preventing a blank dialog

// Before
useEffect(() => {
  if (open && licenseId != undefined) {
    dispatch(loadingLicense({ licenseId }));
  }
}, [open, licenseId, dispatch]);

// After
const { isAuthReady } = useAuthSession();

useEffect(() => {
  if (open && licenseId != undefined && isAuthReady) {
    dispatch(loadingLicense({ licenseId }));
  }
}, [open, licenseId, dispatch, isAuthReady]);

When isAuthReady flips to true the effect re-runs automatically, so there is no change to the happy path for already-authenticated sessions.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• download.cypress.io
  • Triggering command: /opt/hostedtoolcache/node/24.14.1/x64/bin/node /opt/hostedtoolcache/node/24.14.1/x64/bin/node index.js --exec install (dns block)
  • Triggering command: /opt/hostedtoolcache/node/24.14.1/x64/bin/node /opt/hostedtoolcache/node/24.14.1/x64/bin/node dist/index.js --exec install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
