fix: redirect to envelope validation page after signing envelope file

When signing a file that is part of an envelope, the system was
redirecting to the individual file validation page instead of the
envelope validation page. This caused users to see only the single
file information rather than the complete envelope view.

This fix checks if the signed file has a parent envelope and returns
the parent envelope UUID in the response, ensuring proper navigation
to the envelope validation view.
