* op-e2e: Start adopting op-chain-ops

This PR starts the process of adopting op-chain-ops in op-e2e by porting over the `Secrets` struct we use in Hive. This lets us share wallet generation code among different projects.

Adopting op-chain-ops in op-e2e improves the following:

1. Transactions now route through the correct proxy contracts.
2. There's no need to wait for a contract deployment since conracts exist in genesis.
3. We can export the test helpers in op-e2e to enable us to run similar end-to-end tests in other applications like the indexer

This is the first in a series of stacked PRs.
