bug: File duplication upon upload to /files/original/

[CosmoWorker]

Description
While creating a Video Info record, a video is uploaded and saves to public/files/original/ locally. However, the same video file appears duplicated in public/files/. This duplication occurs later in the process when in background, translated video also is saved to public/files/processed/.

Steps To Reproduce

1. Create a new Video Info record and upload a video ( ensure the private is unchecked ).
2. Once uploaded, record is submitted. Then Click the Start Process button.
3. Observe that after uploading and during the translation process, files saved in public/files/original/ and public/files/processed/ also appear in public/files/.

Expected Behaviour
Files stored in public/files/original/ and public/files/processed/ should not be duplicated in public/files/.

As expected, every file upload gets stored in public/files/ by default. The initial intent behind using /processed and /original was to segregate the original uploads from the files that are extracted or generated during the process.
The Frappe framework is working as intended — those additional directories are simply extra copies used in the local setup. So, saving into one of those directories still results in the file being stored in public/files/.

It's more of a trade-off than a bug. Currently, it doesn't break anything or interfere with functionality, aside from causing duplicate files.
A possible fix/enhancement would be to avoid using separate /original and /processed directories, and rely on the default /files/ path — since record names are auto-incremented and uniqueness would be ensured.
