provenance: add label() method, show provenance in history output

Browse source 
Move provenance_label() from query.rs private function to a pub
label() method on Provenance, eliminating duplication. History command
now shows provenance, human-readable timestamps, and content size for
each version.

Handle pre-migration nodes with bogus timestamps gracefully instead
of panicking.
