Pull request overview

This PR adds two new push notification commands (show_camera / hide_camera) that allow the iOS app to present (or dismiss) a full-screen camera player overlay in response to notification commands, extending the existing notification-command pipeline used across APNs and local push.

Changes:

• Extend legacy push payload parsing to support show_camera/hide_camera and include entity_id for show_camera.
• Add new notification command handlers and register them in NotificationCommandManager.
• Add app-side handling to present/dismiss a full-screen CameraPlayerView, plus JSON fixtures for push-server contract tests.
