[SCC Testing] Ethena (Synthetic Dollar)

[mutantcornholio]

• Assess test suite & document
• Assess whether test suite will run on current version of Foundry/Hardhat, document differences
• Get test suite to run on Javascript test framework
• Get test suite to run on complete version of Foundry/Hardhat (with Anvil and Embedded EVM) once ready

All tests fail with StackUnderflow, we aren't taking it to phase 2
