Add Playwright e2e tests for React SDK (redirect + embedded sign-in)

[DonOmalVindula]

Summary

Add end-to-end tests for the @asgardeo/react SDK covering both redirect-based OAuth and embedded <SignIn /> component sign-in flows, running against two identity providers.

What's Included

Identity Providers

• WSO2 Identity Server (wso2/wso2is:7.2.0) — full OIDC provider with DCR, SCIM2, and logout consent
• Asgardeo Thunder - AsgardeoV2` platform

Test Coverage

Test	IS	Thunder
Redirect to IDP login page	Yes	Yes
Sign in with valid credentials (redirect)	Yes	Yes
Redirect unauthenticated users to IDP	Yes	Yes
Sign out and redirect to landing page	Yes	—
Block protected routes after sign out	Yes	—
Render embedded <SignIn /> component	Yes	Yes
Sign in via embedded component	Yes	Yes
Display user profile	Yes	Yes
Navigate back from profile	Yes	Yes

Infrastructure

• Docker Compose setup for both IDPs with health checks
• Automated IDP setup: app registration (DCR/management API), test user provisioning (SCIM2)
• Unified test runner script (pnpm e2e -- --idp is|thunder|all --mode redirect|embedded|all --headed)
• Separate Playwright configs for redirect and embedded modes (Vite bakes env vars at build time)

SDK Fixes

• Fix AsgardeoProvider V2 race condition: loading poll could set isLoadingSync=false before token exchange completes, causing ProtectedRoute to redirect prematurely. Added auth-params guard to prevent this.

Sample App Improvements

• Remove VITE_ASGARDEO_SIGN_IN_MODE custom env var — SignInPage now uses signInUrl from SDK context to determine redirect vs embedded mode (consistent with SignInButton behavior)
• Remove CallbackPage workaround (no longer needed after SDK fix)
• Remove test-only EmbeddedSignInPage
