Feature Request: Support for direct file download URLs including filenames

[orazionelson]

Description

It would be useful if Dataverse could provide direct file download URLs that include the filename in the URL path.

Platforms like Zenodo already implement this feature — for example:
https://zenodo.org/records/17926568/files/Batteries%20as%20Networked%20Fractal%20Energy%20Systems.pdf?download=1

This makes it possible to link to files in a user-friendly way, showing the actual filename in the link.

Current Behavior

Currently, Dataverse provides file access links using only the persistent identifier (PID), as described in the documentation:
https://guides.dataverse.org/en/6.4/api/dataaccess.html#basic-file-access

This results in URLs that do not expose the filename, such as:
https://dataverse.example.org/api/access/datafile/:persistentId/?persistentId=doi:10.xxxx/FK2/XXXXX

Proposed Enhancement

Add an option (or endpoint) that allows direct download links that include the filename in the URL, e.g.:
https://dataverse.example.org/api/access/datafile/${dataverse_id}/Filename.pdf

Use Case / Motivation

• Improves human readability of links shared outside Dataverse.
• Makes it easier to integrate Dataverse files with other systems or websites that expect descriptive file URLs.
• Aligns Dataverse with other repositories such as Zenodo that already offer this feature.
