Store::settle now journals a settlement once, line for line, and one
payment event per application, so replay rebuilds the same tags and the
projection sees the same entry. A single legacy-shaped payment is still
journaled byte for byte; more than one document, a discount or a fee
needs documents_v2, and a payment accepted only because an earlier one
was reversed still needs document_standing.
Each event names the control line it tags (line) and, when it took one,
its discount and discount line; the fee is on the first application's
event with its line. Replay tags exactly those lines and leaves a line it
cannot match untagged, which books.control_check lists; a legacy event
without line keeps the first-untagged-control-line rule.
Tests: a_settlement_names_its_lines_and_replays (two invoices, a discount
and a fee; event indices match the plan; replay equals live),
settlement_waits_for_documents_v2 (refused with the feature remedy and no
journal line, accepted after the upgrade), and
legacy_payment_events_keep_the_positional_rule. arap_props gains a
Settle op (two documents, discount, fee), and
books_written_under_older_rules_still_open gains a hand-written payment
event of the new shape through JournalWriter (8.0.6 item 1).
