caspers_refund_agent is hardcoded

This causes an issue if we have more than one simulation running in a workspace.

1. The second simulation will fail when trying to actually create its own refund agent
2. The rest of the simulation will "work" but be querying the agent deployed by the first simulation. The queries to the agent will work, but the agent won't find anything because its from "the other universe".

We just need to update the name to have the catalog prepended like the other assets.
