Introduce runner controller audit events

What does this MR do and why?

This change set introduces audit events across all runner controller actions. For some actions I've refactored it into a separate service first.

💡 Review commit by commit - changes are repetitive and mostly it's a large change set because of that repetitive service refactoring including boilerplate and audit event definitions.
