Editor-created subdocuments not appearing in trash after deletion

[virgile-dev]

Bug Report

Problematic behavior
When a user with editor permissions (not the owner) creates a subdocument within a document and then deletes it, the subdocument does not appear in their trash. This behavior is inconsistent with what he is prompted in the delete modal.

Expected behavior/code
Any subdocument created by a user, even within a document they only have editor permissions for, should be treated as their property. Deleting such a subdocument should move it to the user's trash.

Steps to Reproduce

1. User A owns a document.
2. User B (editor) creates a subdocument within User A's document.
3. User B deletes the subdocument they created.
4. The deleted subdocument does not appear in User B's trash.

Environment

• Docs version: 5.4.1
• Instance URL: docs.numerique.gouv.fr

Possible Solution
The system should recognize that subdocuments created by a user are their property, regardless of their role in the parent document. Deleting such subdocuments should move them to the user's trash.

Additional context/Screenshots

• This issue affects users who are not owners but have editor permissions.
• Clarifying ownership rules for subdocuments created by editors could resolve this inconsistency.
