Add login page with Sign in with Apple and Google

[muvaf]

Summary

Resolves LIM-285 — Build a login page with Google and Apple ID.

Adds a polished SwiftUI login screen to the sample iOS app with:

• Sign in with Apple using AuthenticationServices (SignInWithAppleButton). Full name and email scopes are requested and propagated to the session model.
• Sign in with Google — pixel‑styled Google button (multicolor G logo, white background, subtle stroke) that drives the local AuthSession. Wiring up the GoogleSignIn SDK requires an OAuth client ID and SPM dependency, which would block this sample app from building without project secrets, so the button uses a local stub. Replacing handleGoogleTap with a GIDSignIn.sharedInstance.signIn call is the only change needed once those are configured.
• Continue with Email placeholder for future email/password flow.
• Status banner that surfaces errors (e.g. Apple cancellation, missing iCloud) inline below the buttons.
• After sign‑in, the app routes to a welcome screen showing the provider, display name and email, with a Sign Out button that returns to login.
• Smooth crossfade animation between login and welcome states.
• Accessibility identifiers on every interactive element to make UI testing straightforward.

Files

• sample-native-app/AuthSession.swift — AuthSession / SignedInUser / AuthProvider model types.
• sample-native-app/LoginView.swift — Login UI, Apple/Google/email buttons, status handling.
• sample-native-app/ContentView.swift — Routes between LoginView and the welcome screen.

Notes

• iOS deployment target stays at 26.0 / 26.2 as before. No third‑party packages or Xcode project changes were required — the project uses PBXFileSystemSynchronizedRootGroup, so the two new Swift files were automatically picked up.
• Build verified with lim xcode build . (succeeded).
• Manual end-to-end test performed with lim ios perform: tapping "Sign in with Google" routes to the welcome screen, "Sign Out" returns to login, and "Sign in with Apple" correctly invokes Apple's ASAuthorizationController.
