Complete a direct multipart upload
Finalizes the multipart upload, verifies the stored object's size against what the session declared, and returns the resulting asset with its capability URL. Requires a workspace member with the `files:write` permission. A session that has expired, been aborted, or is completed with the wrong number of parts is rejected; completing a session that already finished returns the existing asset. Send an `Idempotency-Key` header to make retries safe; a replay within the window returns the original response.

Validates the declared name, MIME type, size, and per-part checksums, checks the workspace storage quota, opens a multipart upload against the object store, and returns the session with one presigned URL per part and an expiry. Requires a workspace member with the `files:write` permission. Refused when the storage backend does not support direct uploads, when the declared metadata or part layout is invalid, or when the workspace is over its storage quota. Send an `Idempotency-Key` header to make retries safe; a replay within the window returns the original response.
Abort a direct multipart upload session
Claims the abort in the database before discarding the object store's multipart state, so it can never race a completion that has already begun, and returns the session id. Requires a workspace member with the `files:write` permission. Naturally idempotent: a session that is no longer uploading is left untouched.
