EPIC: Push migration - API work

[kbelikova-oddball]

Part of Push Migration initiative
Problem to solve:
To enable Push notification migration, API endpoints must be developed and integrated to manage device registration, message delivery, and user preferences for Push notifications. These API enhancements are critical for establishing seamless communication between VANotify and AWS SNS, ensuring scalability, reliability, and secure delivery of Push notifications.

Definition of Done:
• Develop and deploy API endpoints to manage device registration, message delivery, and user preferences for AWS SNS Push notifications.
• Implement robust error handling and logging to track and resolve API-related issues.
• Conduct end-to-end testing to confirm APIs meet performance and reliability standards.

Key Results:
• API successfully supports Push notification delivery via AWS SNS for 100% of registered devices.
• API uptime maintained at 99.9% or higher.

What We Want to Avoid:
• Performance issues with VANotify due to improper API integration with AWS SNS.
• Lack of clear documentation or processes for maintaining and scaling the APIs.
