Statements checked against their lines and the P&L

For each statement in the window, two checks with their denominators: (1) TikTok against itself — the statement's settlement_amount minus the sum of its own lines, computed only once every line has landed; (2) linkage — which order and adjustment ids on the statement also appear on P&L rows tagged with this statement id, counted per id, never by money. States: incomplete, no_overlap, partial, complete. Read the counts before the state: a no_overlap on a shop whose P&L export has never run means nothing about the statement. Each page costs three reads, so limit is capped at 50.
