test: add React Native remote push E2E (MBL-2302)

[Shahroz16]

Summary

• add a local or trusted-CI Maestro flow for real React Native APNs delivery and opened-attribution validation
• identify a fresh profile, wait for its iOS device registration, trigger the dedicated Maestro React Native APNs E2E automation (campaign 68), and verify the exact event reached Customer.io
• require delivered, capture a non-empty message ID, activate the real system notification, and require opened for that same message ID
• build the existing APN sample and notification service extension with matching ignored local configuration, without committing credentials

Stack

Stacked on #643. That PR provides deterministic scene-configured notification routing coverage. This PR adds the separate remote APNs delivery and attribution loop.

Scope

This is APNs-only validation. It does not claim FCM, deep-link destination routing, or multiple-push-provider coverage. No credentialed PR workflow is added.

Validation

• Release simulator build of the React Native APN sample and notification service extension passed
• fresh profile creation, iOS device registration, exact event ingestion, campaign 68 delivery, physical notification activation, and backend opened attribution for the same message passed against the Mobile: React Native workspace
• Bash syntax, ShellCheck, ESLint, pre-commit, pre-push, and diff checks passed
• credentials and raw artifacts remain ignored; exported artifacts are redacted before copying
• independent adversarial review findings around registration proof, artifact handling, simulator ownership, and shared-campaign overlap were addressed

Remaining automation boundary

Maestro 2.8.0 sees the exact SpringBoard notification on iOS 26.5, but its tapOn command does not activate that system notification cell. A physical accessibility click opens the app and records both human_opened and opened, so the SDK/backend path is verified, but the fully unattended Maestro loop is not. This PR remains draft until that system-UI interaction is deterministic; the assertion is intentionally not weakened.
