feat: toggle settlement health event upon settlement batch submission status

[omritoptix]

Overview

This pr moves the batch submission to settlement layer logic from the manager to the settlement.
By that it allows us to encapsulate the logic and handle any possible failures.
The manager will only be notified upon submission success or health status changes.

IMO it's bad practice
