ctp: delete hardhat drippie tests

contracts-periphery: foundry tests for drip checks

Add foundry tests for the dripchecks. Each test suite
includes a fuzz test for the positive and negative cases.
This is a continuation of porting all contracts tests
to foundry for a unified developer testing environment.

feat(ctp): audited Drippie mainnet deployment

The foundry tests merged in https://github.com/ethereum-optimism/optimism/pull/4760
are a superset of the hardhat tests so we can delete the
hardhat drippie tests in favor of the foundry based tests.
This is moving us closer to a unified smart contract
development environment where we can enforce the same standards
across all smart contracts developed in the monorepo.
