ios: use deadline-based retry for simulator app launch

The fixed-attempt retry (5 attempts, ~12s window) is too short for CI
simulators where SpringBoard needs 30-60s after boot to accept app
launches — especially when the build step is cached and provides zero
warm-up time.

Switch to a deadline-based approach matching ensureBootedSimulator:
- Default 30s timeout (configurable via AGENT_DEVICE_IOS_APP_LAUNCH_TIMEOUT_MS)
- CI sets 60s to handle cold-boot scenarios
- maxAttempts set high (30) so the deadline is the real limit
