[RunConv][Backend] Provide download link for run history (direct export to file)

As a Data Preparation user,
I want to download the result file of a preparation full run from the history page (when exporting directly to a file),
in order to retrieve the result of my preparation for further usage without creating a dataset (similar usage as in current legacy mode).

[backend API part]

Scope: Runs in Runtime Convergence mode

• For direct export to a file without selecting a dataset as destination
• For datasets => implemented in TDP-9974
• For legacy runs => implemented in TDP-9964

Why?

A new run history API in Preparation V2 now provides the list of runs for a preparation both in legacy mode and runtime convergence mode.

Data Preparation backend needs to provide a download link to access it from the frontend (Run history page).

How ?

Implement /transform/preparations/{preparationId}/runs/{runId}/content endpoint (see API Designer spec) on runtime convergence mode

• For direct export to a file without selecting a dataset as destination => store file on MinIO and return a presigned URL
• See how to generate presigned URL (use AmazonS3.generatePresignedURL(...))
• Set expiration time to 1H (odubois See dataset policy?)
