Deletes a file and its associated keys from the project.

Project Type Compatibility:

• ❌ Software projects (localization_files) - File deletion not supported for Software projects
• ❌ Documents projects (paged_documents) - Branching not supported for Documents projects
• ❌ Marketing projects (content_integration, marketing, marketing_integrations) - Branching not supported for Marketing projects

Note: This endpoint requires branching support, which is only available for Software projects. However, Software projects do not support file deletion. This creates a logical conflict - this endpoint may not be practically usable.

Requires write_files OAuth access scope.
