chore: migrate tests to solidity

[mfw78]

Description

There is a comprehensive test suite that needs to be migrated from hardhat to foundry.

External contributors

Upon completion of reference unit test and/or reference E2E test, external contributors are invited to contribute to the code base in the migration from hardhat to foundry for subsequent unit / E2E tests.

Work plan

1. Assign yourself to a task (or external contributors, request assignment)
2. In accordance with best practices, implement the nominated hardhat test suite in foundry.
3. Code coverage must be equivalent.
4. The submitted PR must have:
   a. The foundry tests
   b. Deleted the associated hardhat tests that were migrated
   c. Run forge fmt on the source code files that were added.
