fix(created-by-sources): Adding created_by to sources

[phixMe]

Problem

We aren't attributing users to sources at this time and the column is just null in every case.

No updates for the UI as we're actually going to be missing this data for everything created before this is merged, but better to capture the data now then capture for everything moving forward.

Current Situation:

{
    "id": "01948a8e-9f5c-0000-f256-b89f1462cdd3",
    "created_at": "2025-01-21T20:29:50.300616Z",
    "created_by": null,
    "status": "Running",
    "source_type": "Postgres",
    "prefix": "",
    "last_run_at": null,
    "schemas": [
        {...}
    ]
}

Changes

• Add field to creation id
• Hydrate id to object in response

Does this work well for both Cloud and self-hosted?

Yes

How did you test this code?

API works and correctly links the id --> email once it's returned to the user.
