fix: harden iOS alert smoke scenario

[thymikee]

Summary

Harden the fixture-backed iOS simulator alert smoke scenario against UI timing races.

The scenario now waits for the alert trigger to be visible after scrolling, waits for an app-visible opened canary after the click, defers native alert presentation by one frame, and gives XCTest a bounded 10-second alert wait.

Root cause

The failed job reported a successful click, but XCTest never observed the native alert during the 5-second query window. The preceding UI was not independently synchronized with the React Native state transition, making this a timing-sensitive failure.

Validation

• pnpm format
• pnpm typecheck
• pnpm exec oxlint examples/test-app/src/screens/AutomationLabScreen.tsx test/integration/ios-simulator-e2e/live-automation-scenario.ts
• node --experimental-strip-types --test test/integration/smoke-ios-simulator-coverage.test.ts (14/14)
• Expo test-app typecheck was not run locally because its isolated dependencies were unavailable and npm registry access failed.

Exact-head review at 93a95bf0: the fixture/smoke hardening is coherent and no code finding remains. The scenario now proves trigger visibility, proves the click reached React state, then waits for the native alert with a bounded deadline; all code, integration, and Android/iOS/macOS/Linux smoke lanes are green. The lone red native-fingerprint job failed because the trusted-artifact lookup returned fetch failed, an infrastructure failure unrelated to this two-file test-app delta. Rerun that job; apply ready-for-human once the exact head is fully green.
