ci(e2e/ios): Debug build with embedded JS + mock web-auth transport for social test

Release embeds the JS bundle but disables the SDK's mock web-auth transport
(FronteggRuntime.allowsTestingWebAuthenticationTransport is #if DEBUG), so the
Google social-login smoke test hit a real ASWebAuthenticationSession that can't
complete headlessly in CI. Switch back to a Debug build (mock transport available)
and make the app self-contained without Metro:
- build with FORCE_BUNDLING=1 so the Debug app embeds main.jsbundle
- AppDelegate loads the embedded bundle under test (frontegg-testing=true)
- launchApp gains a useTestingWebAuthenticationTransport flag
- LoginViaGoogleTest launches with the mock transport so the social flow completes
  against the local mock server instead of a real Safari VC
