feature: bootup db integrity check

[prestwich]

Motivation

Prevent agent from accidentally being run with different contract addresses that previous invocations. This will prevent manual config wrangling from accidentally triggering severe agent issues

Solution

Add a bootup integrity check. This check stores the core contract addresses in the DB, keyed by network, and checks the config addresses against the DB at each bootup.

TODO: figure out how to disable integrity check in tests 🤔
