Delta review fixes:
- ReleaseRenest throws when a commit does not call finish, or calls it
twice: either would leave ledger plates uncoded or count a sheet twice
for later nests of the run. The ledger sheet count is the codes given.
- A stage whose layout is not kept now lists the copies its layout
missed with their own reasons (a part no sheet fits stays "does not
fit"); only the copies it placed are "the proposal cannot be kept".
- A valid ledger layout that places nothing says "Auto Nest placed
nothing on it" rather than claiming no part fits.
- ReleaseLedgerOffer rejects null rows; docs list every ledger note.
