Deletes one or more files from a namespace in document storage (S3). The namespace must belong to the authenticated user. Supports single-file or multiple-file deletion in one request.
Deletion is permanent (S3 DeleteObject). Deleted files are not moved to a trash. You can only delete files in namespaces you own.
You can specify files in the body and/or via query; all are collected and deleted in one call. At least one of: body fileName, body fileNames, or query fileName is required.
One entry per file. Each has fileName, status ("deleted" or "error"), and message. If a file does not exist, that entry has status: "error" and message: "File not found"; other files are still processed.
