Implement Serializer Strategy Across Project

[Daniel-VM]

We will refactor the project to implement a modular serializer strategy.

Approach

• Queries and operations (services.py) – Centralized DB queries.
• Serializers (serializers.py) – Standardized data formatting.
• Views (views.py) – Handles requests, calls queries & serializers.

Tasks

• Refactor views to use queries & serializers.
• Ensure modularity and consistency.
