fix: Converts ethics system to generic entity persistence (#1824)

### Summary

Converts ethics system to entity persistence and removes the persistence item.


### TODO

1. The enable/disable toggle doesn't propagate to all code that does Ethics checks (notoriety, pvp, etc).
2. We need commands to remove them from an ethic.
