Not passing real Response Body File Paths to Frontend

[SoulKa]

We're currently keeping the absolute file system path to the response body file on the TrufosResponse object. We're already using IDs for requests to prevent passing file paths to the frontend and should do the same for the response. This way, we're flexible about the handling of the response body storing logic and follow electrons recommendation on file paths in frontend.

Acceptance Criteria

• The TrufosResponse does not contain real filepaths
• The response body loading/displaying still works
