Refactor Endpoints to Support Multiple Indexes Dynamically in finesse-backend

[k-allagbe]

Description

Our backend currently has hardcoded endpoints for specific indexes. As we're adding more indexes, this setup will be hard to maintain. We need a flexible endpoint system that can handle different indexes based on the request details, without needing hardcoded paths for each one.

Tasks

• Review the existing endpoint implementations.
• Design a generic endpoint system that can dynamically adjust to handle different indexes based on input parameters such as index type or name.
• Implement the new endpoint system, ensuring it supports all existing functionalities and can easily scale to include new indexes.
• Test the new endpoint system.
• Update all relevant documentation and API usage guides.

Acceptance Criteria

• The backend must dynamically adapt its endpoints to handle requests for any specified index without hardcoding for specific indexes.
• The new system must maintain all existing endpoint functionalities and seamlessly integrate new indexes.
