docs(backlog): mark Wave 10 items DONE; final grand-audit status
Wave 10 closed four more audit dossiers via:
- 10.1 types-auditor (Tx type, BerthDetailData, parseBody, toAuditJson)
- 10.2 build-auditor (server externals, healthcheck, NEXT_PUBLIC_APP_URL)
- 10.3 concurrency-auditor (handleDocumentCompleted TOCTOU, moveFolder
cycle race, upsertInterestBerth + username 23505 mapping)
- 10.4 aria-hidden mechanical sweep across 267 files
Grand-audit status: every dossier from AUDIT-2026-05-12.md (27 reports)
has either its CRITICAL+HIGH items shipped or is explicitly back-
burnered for the four user-deferred reasons (Documenso phases 2-7,
bounce monitor, manual QA, BullMQ jobId plumbing).
