Automate etherscan verify as a githook and add as a merge blocking condition

This is an important step to allow Decentralised Contract Deployment, as we have separated deployment from verification, and can be sure what's checked into git is what's deployed on mainnet/testnet.

I am interested in picking this up but want to make sure that I am understanding the ticket correctly.

Whenever there is a new deploy of contracts helper.ts should be updated. What we want to add is that if the constants mentioned here are changed because of a new deployement, there should be a githook that blocks merging to the main branch if it is not verified?

There should be a way to verify it programmatically in hardhat: https://youtu.be/gyMwXuJrbJQ?t=31875
