Consider adding anvil contract integration tests

[ECWireless]

Is your feature request related to a problem?

• Currently there is no way for developers to test transaction flows before deployment without manually testing everything on a production chain
• The last testnet chains available in the explorer were goerli and rinkeby, but these are now deprecated

Describe the solution you'd like

• We should add integration tests for all transaction flows using forked anvil contracts: https://www.getfoundry.sh/anvil#common-workflows
• These forked anvil contracts will simulate actual protocol contracts that exist on Arbitrum
• These tests should run in the CI, and be required to pass before any PRs are merged

Describe alternatives you've considered

• Adding new Sepolia contracts were considered. However, forked anvil contracts should do the trick with even less work
