API Harmonization server

The API Harmonization server is the backend layer of O2S, responsible for aggregating, normalizing, and orchestrating data from multiple APIs. Instead of integrating various services directly into the frontend, the server acts as an intermediary component, ensuring that data is structured in a consistent, API-agnostic format before being consumed by the frontend.

This approach decouples the frontend from backend dependencies, enabling flexibility in swapping or modifying integrations without affecting the UI layer. The server is built using NestJS and provides a modular structure for managing integrations efficiently.
