Report-api : 🚀 Migrate from DynamoDB to Open-Source Supabase

[Yashwanth-79]

This PR migrates our backend database from AWS DynamoDB to Supabase, an open-source alternative based on PostgreSQL. The migration includes:

• Refactoring database operations to use Supabase SDK instead of boto3 (DynamoDB).
• Updating API endpoints to interact with Supabase tables.
• Modifying data retrieval and storage logic to align with relational database structures.
• Updating .env files to store Supabase API URL and keys.
• Ensuring compatibility with existing features and queries.

Benefits of Migration:

1️⃣ Cost-Effective & Open-Source: Supabase eliminates AWS DynamoDB costs while providing a transparent, self-hostable alternative with PostgreSQL’s reliability.
2️⃣ Improved Query Capabilities: Unlike DynamoDB (NoSQL), Supabase supports SQL queries, allowing for better filtering, joins, and complex data relationships.
