Refactor: Unify command menu item execution (#18908)

- Makes engineComponentKey non-nullable on CommandMenuItem. Adds two new
engine component keys: TRIGGER_WORKFLOW_VERSION and
FRONT_COMPONENT_RENDERER to cover the former standalone cases.
- Unifies the previously separated engine, front component and workflow
runners into a single `CommandRunner` component with a unified
`useMountCommand` hook that handles all command types.
