Create use case for getting file type search results in a collection

[ekraffmiller]

For the Collection page, we need to display the files that belong to the collection.
The file items will be read from the search results of that collection, and be returned as FilePreview objects.

Here is a sample search result for file type:

 {
        "name": "MetaVideoGame2011-04-27_2011-04-30.tab",
        "type": "file",
        "url": "http://localhost:8080/api/access/datafile/12",
        "file_id": "12",
        "description": "Metadata video description",
        "published_at": "2024-07-29T18:12:42Z",
        "file_type": "Tab-Delimited",
        "file_content_type": "text/tab-separated-values",
        "size_in_bytes": 1978,
        "md5": "baaddf33c34f281d8b5c8c6adec30a1a",
        "checksum": {
          "type": "MD5",
          "value": "baaddf33c34f281d8b5c8c6adec30a1a"
        },
        "unf": "UNF:6:zFwFCrc+bxF7TBUNdf7vTw==",
        "dataset_name": "Second Dataset",
        "dataset_id": "11",
        "dataset_persistent_id": "doi:10.5072/FK2/SZZHLN",
        "dataset_citation": "Admin, Dataverse, 2024, \"Second Dataset, with updated\", https://doi.org/10.5072/FK2/SZZHLN, Root, DRAFT VERSION, UNF:6:zFwFCrc+bxF7TBUNdf7vTw== [fileUNF]"
      },

• In addition to what is currently returned, the SPA needs the publication status of the file. This is not currently in the Dataverse Search API, an issue was created to add this https://github.com/IQSS/dataverse/issues/10733

@ekraffmiller In this issue we can include publicationStatus, both for datasets and files, without having to create a separate issue, since in this issue the use case and models for the collection results will be modified.
