M12f: S-16 lost version read-only, S-22 versions from /health, settle start without a partner (D-109 to D-111)

- Rejection.lost: RejectedVersion (the pushed entity from sync_rejections.rejected_payload as a ledger row, account,
  payer, split, notes, deleted); S-16 "Öppna" shows it read-only in a dialog with "Visa nuvarande version" (S-8/S-10);
  without one it opens the current version as before. Ledger rows take a null onClick (read-only).
- AboutState.schemaVersion; AboutRepositoryImpl calls E-1 /health once per collection when online; header fallback.
  S-22 shows "1.1.0 (schema 3)".
- SettlementRepository.start/recompute return null without a session or partner; save is Invalid(payer); no
  checkNotNull/requireNotNull in :data.
- :feature:home screenshot harness: one more frame and an idle looper before each capture; the committed sv_dark,
  200 % and dialog goldens were one variant stale (light instead of dark, en instead of sv_200).
- Tests: lost version (stale, refused deletion, unreadable payload), /health online and offline, settle without a
  partner, category reorder PATCHes, recurring toWire splits, §9.2 effect cases.
