fix(production): preserve completed state after defect reversal

[cb8010d6]

Problem

Reversing an earlier defect-only report could downgrade a completed work order to IN_PROGRESS even though net good quantity still met planned quantity.

Change

Derive COMPLETED first from the same net-good-quantity rule used by report posting; preserve existing PENDING/IN_PROGRESS behavior otherwise. No changes to inventory, transactions, outbox, idempotency or accounting policy.

Validation

Regression reproduced before fix. Five new cases cover completed defect-only reversal and replay, good-quantity reversal reopening, remaining active reports, partial quantity and final defect-only reset. Local API full suite 665 tests, typecheck and changed-file lint passed. Independent Astra review and 26 focused production tests passed.

Stacked on #42. Exact head 4729940788912acd6d2c31cfddb4c2e5c93f8928 passed all gates in CI run 36288237961: 825 regular tests (18 scripts + 665 API + 142 Web), 77 real PostgreSQL regressions, 13/13 stocked-trade HTTP steps and 9 actual Chromium tests. Actual logs inspected. No deployment/main merge or production-readiness claim.
