- Set explicit timeout of 70 seconds for button click operation
- This is 10 seconds more than the 60-second final response timeout

- Ensures button click waits long enough for slow-loading pages
- Addresses user feedback about button selector timeout issues

The timeout hierarchy is now:

- Main JSON detection: 45 seconds
- Container selector: 48 seconds
