feat(audit-cleanup): finish all 15 outstanding items from verified backlog

Audit cleanup completion plan, all tiers shipped:

Tier 1 (security + data integrity)
- A.7 RTBF true wipe: redact email_messages body/subject/addresses for
  threads owned by deleted client; redact document_sends.recipient_email;
  collect file storage keys + delete blobs post-commit.
- A.8 user_permission_overrides FK: documented inline why cascade is
  correct (not set-null as audit suggested) — overrides have no value
  without their user.
- W2.14 PII redaction: camelCase normalization in audit.ts +
  error-events.service.ts isSensitiveKey; added city/postal/country/
  birth fragments. firstName/lastName/dateOfBirth/postalCode etc. now
  caught in BOTH masker paths. 12 new test cases lock the coverage.

Tier 2 (Documenso completion + refactor)
- C.2: documentEvents.recipient_email column + partial unique index for
  per-recipient webhook dedup (migration 0075). handleDocumentSigned
  now sets recipient_email on insert.
- Phase 2: completion_cc_emails distribution. handleDocumentCompleted
  reads documents.completionCcEmails, filters out signer-duplicates
  case-insensitively, fans signed PDF out to non-signer recipients.
- C.4: extracted createPublicInterest() service from the 346-line
  api/public/interests route. Route becomes a thin shell (rate-limit,
  port resolution, audit log, email fan-out). The trio creation logic
  is now unit-testable without an HTTP fixture.
- Phase 4: POST /api/v1/document-templates/[id]/detect-fields wired
  to document-field-detector.detectFields(). Sparkles "Auto-detect"
  button added to template-editor.tsx — maps DetectedField → marker
  with best-guess merge token (DATE / NAME / EMAIL); user retags.

Tier 3 (reporting + recommender snapshot lockfiles)
- W7.reports: extracted rollupStageRevenue / rollupStageCounts /
  computeTotalForecast / computeOccupancyRate / rollupBerthStatusCounts
  into src/lib/services/report-math.ts (pure functions). 16 new tests
  including an inline-snapshot lockfile on a representative 7-stage
  forecast. report-generators.ts now delegates.
- W7.recommender: 18 new toMatchSnapshot tripwires on classifyTier
  boundaries + computeHeat at canonical input points.

Tier 4 (rolling)
- W6.attach: fixed outdated CLAUDE.md claim — threshold banner is
  informational and never depended on IMAP; bounce monitoring (the
  IMAP poller) is separate.
- D.1 + D.2: documented deferral inline with full why-not-build-it
  reasoning so a future engineer sees the rationale.
- G.1: representative formatDate sweep (audit-log-list, user-list,
  document-templates merge tokens, document-signing email). Rest of
  the ~100 sites stay rolling.

Quality gates: 1420/1420 vitest (46 new tests above baseline of 1374),
tsc clean, 0 lint errors.

Plan: docs/superpowers/plans/2026-05-18-audit-cleanup-completion.md
Migration: 0075_c2_document_events_recipient_email.sql (applied to dev DB).

+/**
+ * Bulk-import worker — DEFERRED FEATURE (placeholder).
+ *
+ * Status: registered with BullMQ so any future enqueue site lands on a
+ * real worker instance instead of disappearing into an unbound queue.
+ * No callers currently dispatch to this worker — the body is intentionally
+ * a no-op that logs the dispatch for forensics.
+ *
+ * Why deferred (vs implemented inline):
+ *   - CSV/Excel import is a real product feature, not a refactor. Done
+ *     properly it needs: per-entity schema mapping (clients / berths /
+ *     interests / companies / yachts), zod-level row validation, per-row
+ *     error rollup with line-numbered diagnostics, dry-run preview,
+ *     progress reporting, dedupe-on-conflict policy, admin upload UI
+ *     with column-mapping UX. Building it speculatively without a
+ *     customer in the room would lock in a UX that may not match what
+ *     real importers want.
+ *   - When the trigger comes (a customer needs to bulk-load a season
+ *     roster or migrate from another CRM), build it from product spec
+ *     not from this placeholder.
+ *
+ * What's required to ship: papaparse (CSV) + a thin schema-per-entity
+ * mapping layer, plus an admin /admin/import page with a per-entity
+ * picker + file dropzone. The queue registration here stays as-is.
