Subject: [PATCH] Refactor API calls to use a generic handler

refactor: consolidate API service layer with generic handler

- Fix template literal syntax errors in all API endpoints
- Create reusable handleApiCall() function to eliminate code duplication
- Initialize axios instance with baseURL, timeout, and default headers
- Standardize error handling and response formatting across all endpoints
- Organize endpoints by feature (auth, users, files, posts)
- Improve error logging with method and endpoint details

Reduces code by ~70% while improving maintainability and consistency.
