Add API request/response logging for debugging and monitoring

**Description:**
To improve traceability and debugging of OCR and video processing, we should log incoming API requests and their responses. This will help developers identify:

- When and how API endpoints are hit
- What data is being sent and returned
- Failures, exceptions, and response codes

****Scope of Work**:**

-  Set up logging in framegrabber/settings.py
-  Log request method, URL path, timestamp, and status code
-  Add logging calls in key views (e.g., video upload and OCR processing)
-  Ensure sensitive data is not logged

**Purpose of Work:**

This will help:
- Debug issues in production or development
- Monitor endpoint usage
- Improve reliability and future scalability
