[WIP]: Migration to hardhat-viem

[rin-st]

Description

Migration to hardhat-viem

Todos:

• use viem an hardhat-viem in scripts and deploy files
• generating deployments folder.
• fix verification
• fix type errors
• refactor listAccounts
• migrate tests

Notes:

• since hardhat-viem is a "new shiny lib (c)", some things is not working as expected, for example types. Also we need to replace hardhat-deploy-ethers and I think some other plugins too, but I'll try to go without it (probably Ignition can help, but we need to wait until they'll add viem support. Currently only ethers v6)
• after removing hardhat-ethers/hardhat-deploy-ethers deployments folder isn't generated automatically. So I needed to do it in order to create next/generated/deployedContracts folder. It caused adding generateDeployments() to deployYourContract. I'll think again and try to find alternatives. Feel free to add thoughts and ideas about it.

Additional Information

• I have read the contributing docs (if this is your first contribution)
• This is not a duplicate of any existing pull request

Thanks for working on this, Rinat!

Yeah, I guess waiting for Ignition to support Viem could be the way to go (rolling our own stuff might be too hardcore)

Maybe we just need to wait until hardhat-viem is more stable + ignition supports viem? If not, it seems that we'd need to have ethers & viem at the same time, or roll our own deployment workflow.

What do you think?

Basically, things mostly works already. But

• as I said already, I need to manually create deployments folder in order to create generated/deployedContracts for nextjs
• hardhat-verify also works, but from scripts or using cli with adding deployed address and params.

So it's just workarounds, not something convenient and stable. Ignition will help with first issue and hopefully with second too. I'll continue to experiment with it, but for now yes, looks like we need to wait for ignition and more stable versions
