PreviewURL use cases and extension on dataset and file use cases

[ChengShi-1]

What this PR does / why we need it:

• Datasets/Files: Added optional Preview URL (previewUrlToken) support to getDataset, getDatasetFiles, getDatasetFileCounts, getDatasetFilesTotalDownloadSize, getFile, and getFileAndDataset
• Datasets: Added createPreviewUrl, getPreviewUrl, and deletePreviewUrl use cases

Which issue(s) this PR closes:

• Closes Extend Dataset and File use cases: add privateUrlToken #470

Related Dataverse PRs:

• Depends on #

Special notes for your reviewer:

• toApiQueryParams is needed because the internal query object uses previewUrlToken, but the actual Dataverse API expects that token as query param key. Thus, I mapped key to previewUrlToken for better clarification.

Pull request overview

This PR extends the datasets and files read APIs to support Dataverse “Preview URL” access via an optional previewUrlToken (mapped to the Dataverse key query param), and adds a full Preview URL lifecycle (create/get/delete) to the datasets API surface.

Changes:

• Add optional previewUrlToken support to dataset/file read use cases and repository methods, including mapping to key query param and adjusting auth requirements.
• Add Preview URL lifecycle support (createPreviewUrl, getPreviewUrl, deletePreviewUrl) including a new PreviewUrl model and response transformer.
• Update unit/integration tests, docs, changelog, and test TypeScript config to cover new behavior.
