[wip] feat(anvil): migrate tests to alloy

[Evalir]

Motivation

migrates all anvil tests to alloy. wip.

Solution

[Evalir]

Currently blocked on:

• alloy-sol-contract to replace abigen! & deploy test contracts
• Finalizing call builder to build signable & sendable transactions through an alloy Provider
• Subscriptions functionality

[Evalir]

Continuing by introducing alloy-contract everywhere we can, and switching to just using alloy types and converting as needed. We're lacking the functionality to deploy/send txs which is being worked on alloy-rs/alloy#190. A good amount of usage is actually calls, so we can make good progress while this settles.

Subscriptions are also still WIP, although this is the last thing we'll integrate.
