Describe the bug

As part of v.1.9.6 through this PR, forge-std deprecate MockERC20.sol and MockERC721 (among other things) which we leverage in some tests

@kopy-kat to address this, I think we can integrate OpenZeppelin's or Solady's ERC20Mock by including these mocks in packages or by adding sources locally/writing our own contract within modulekit. What do you suggest?

I think going with solady would make sense

It looks like Solady’s published package does not include mocks by default, and other similar packages based on Solady also exclude them.
To work around this, I installed Solady using Forge with: forge install Vectorized/solady

This method works, but it pulls in the entire Solady repository into the lib folder, even though we only need the mock contracts. This significantly increases the project’s size.
I’ve implemented this approach and can submit a PR if you approve. However, I’d recommend directly adding only the source files for the two mock tokens we require instead, as it would keep the project small while ensuring we have exactly what we need. Let me know what you think!

yeah good point. I agree, copying over the mock erc20 seems like the best idea in that case

Sounds good, pushing this
