Copying a content with binary fields with same name files, duplicates files for all binary fields

Problem Statement

If you create a content type with several binary fields, and for each of them you upload a diff file with the same name when copying the content it puts the same file (last one found) for all the fields.

Steps to Reproduce

1. Create a content type with 3 binary fields and a title field.
2. Create content with 3 diff images but all have to have the same name.
3. Copy the content.
4. Check that for all the fields are the same (this is the issue).

Assumptions & Initiation Needs

No response

Sub-Tasks & Estimates

No response

No source files or tests are named. Start by reproducing the issue with three binary fields and same-named files in the listed dotCMS versions, then trace the content-copying path. Done means each copied binary field retains its corresponding original file rather than sharing the last file found.
