fix(api,orchestrator): fix remaining dependency injection issues

API:
- Add AuthModule import to JobEventsModule
- Add AuthModule import to JobStepsModule
- Fixes: AuthGuard dependency resolution in job modules

Orchestrator:
- Add @Optional() decorator to docker parameter in DockerSandboxService
- Fixes: NestJS trying to inject Docker class as dependency

All modules using AuthGuard must import AuthModule.
Docker parameter is optional for testing, needs @Optional() decorator.
