fix(integration): webhook v2 events, storage migrate, test theatre

- F1: DOCUMENT_DECLINED handler (v2 Decline vs Reject) — routes to same
  handler as DOCUMENT_REJECTED until product refines downstream UX
- Add RECIPIENT_VIEWED / RECIPIENT_SIGNED v2-alias cases with telemetry
  logging so we see when v2 deployments emit them
- D1: populate TABLES_WITH_STORAGE_KEYS (files, berth_pdf_versions,
  brochure_versions, gdpr_exports) — was an empty list, migrated 0 files
- MinIO putObject/getObject/statObject/removeObject socket timeout wrapper
  to prevent worker hangs on TCP blackhole (30s deadline)
- E1: convert test.skip on smoke-setup infra failure to throw new Error
  so green-skipped silence becomes a real test failure (Playwright
  doesn't expose vitest's expect.fail)
- Regression tests: folderId='' → null transform, applyEntityRestoredSuffix
  no-op (never-archived), syncEntityFolderName collision loop past (2)

Note: matching .env.example documentation (D2 — bare DOCUMENSO_API_URL,
DOCUMENSO_API_VERSION, MINIO_AUTO_CREATE_BUCKET, DOCUMENSO_TEMPLATE_ID_EOI,
recipient role id vars) prepared but not committed — pre-commit hook
blocks .env*. Apply manually via the separate .env workflow.
