Proposal information - created/updated dates seem to be reversed

[JunAishima]

For the example v1/proposal/312064 endpoint on api-dev, the output shows:

(truncated)

      {
        "saf_id": "310638",
        "status": "EXPIRED",
        "instruments": [
          "FMX"
        ]
      }
    ],
    "created_on": "2024-02-14T20:00:04.711216",
    "last_updated": "2024-01-08T18:15:35.114000"
  }
}

also, v1/beamline/name has similar output at the end:

      "name": "xspress3",
      "directory_name": "xspress3"
    },
    {
      "name": "merlin",
      "directory_name": "merlin"
    }
  ],
  "created_on": "2024-02-14T20:03:29.175304",
  "last_updated": "2021-09-23T16:35:21.832000"
}
