[validator] run validator automatically on op-acceptor startup

**Is your feature request related to a problem? Please describe.**
We want to run op-validator automatically against any deployment we make (e.g. make it part of the RRC).

**Describe the solution you'd like**
Ensure that we can run op-validator whenever op-acceptor starts, this will ensure we run against any devnets.

**Describe alternatives you've considered**

**Additional context**

Start by locating the op-acceptor startup entry point and how op-validator is invoked in the repository. Trace the RRC or devnet deployment path to understand the required configuration and execution flow. Done means op-validator runs automatically whenever op-acceptor starts and validates each deployment.
