fix: add timeout and error handling to cv-process route

- Add 60-second timeout to prevent hanging API calls
- Add proper error handling and logging for debugging
- Browser was getting 404 because startProcessing was hanging indefinitely
- This will either complete successfully or fail with proper error response
