Implement Structured Request/Response Middleware System

[Abhay-2811]

Currently, the API endpoints handle errors and responses individually, which can lead to inconsistent error handling and response formats. We need to implement a structured middleware system to standardize our API responses.

Proposed Changes:

1. Create a centralized response handler middleware that includes:

   • Standardized success/error response format
   • HTTP status code mapping
   • Error code catalog
   • Request validation middleware

2. Implement structured error types

3. Create response formatter

Expected Outcome:

• Consistent error handling across all endpoints
• Detailed error tracking and logging
• Improved debugging capabilities
• Better client-side error handling

Acceptance Criteria:

• Implement central error handling middleware
• Create error code catalog
• Add request validation middleware
• Update all endpoints to use new system
• Add comprehensive error logging
• Document error codes and responses

Note: This issue is to be merged on main branch so make sure to edit test cases to follow changes. Try to take a modular approach and use akavesdk to verify error codes each command can throw.
