Callback is not triggered after a document is signed #8497

Problem

The callback configured through request-signature is not triggered after the document is signed.

The signing flow stores completion through signedNodeId / signedHash, while the callback listener currently checks a field that is not updated by the File entity.

Expected behavior

When a document reaches the signed state, the configured callback should be notified once with the signed document information.
