fix: extend timeout for Circom proof visibility assertion in E2E test

- Increased the timeout for the visibility check of the "Circom Proof" element from 30 seconds to 60 seconds in the Circom proof test configuration.
- This change aims to enhance the reliability of the test by allowing more time for the element to become visible before proceeding with assertions.
