fix(core): correctly set Listener.handleNewSignedBlockfrom's spanStat…

…us from returned error or panics

This change ensures that if a panic occurs, that span.RecordError
correctly records it and then if an error is returned that span.Status
correctly captures and records it.

Fixes celestiaorg#3814
