remake SysListLoaderAlg into SystematicsSvc
For now this just replaces the algorithm with a service, and communicates the systematics list via the service interface instead of via the event store.
The plan is to add more functionality in future merge requests that will move a lot of the systematics handling functionality from the configuration layer into the service.
It also involves some rework of dual-use services, as this is now the first widely used dual-use service, so I had to make sure the configuration works properly, and clean up the interface-id handling a little bit.
