fix(documents): keep an incomplete extraction on the document

A long document read in parts can end with a part cut at the provider's
output limit, a part never read, or more facts than one review takes.
That was told once, as a notice when the run finished; a review opened
later looked complete.

InboundDocument.extractionIncomplete (migration 0483) is written with
the facts by both stagings, the extract route or run and lab
auto-staging. The document detail publishes it and the review shows the
same note whenever it is opened. The disaster-recovery backup carries
it; an older file restores it as false.
