Matt Ciaccio 83239104e0 fix(audit-tier-6): validation, perms, ops/infra, per-port webhook secret ...

Final audit polish — closes the remaining LOW + MED items the previous
tiers didn't reach:

* Validation hardening: me.preferences uses .strict() + 8KB cap
  instead of unbounded .passthrough(); files.uploadFile gains
  magic-byte verification (jpeg/png/gif/webp/pdf/doc/xlsx); OCR scan
  endpoint enforces 10MB cap + magic-byte check on receipt images;
  port logoUrl + me.avatarUrl reject javascript:/data: schemes via
  a shared httpUrl refinement.
* Permission gates: document-sends/{brochure,berth-pdf} now require
  email.send (was withAuth-only); document-sends/{preview,list} on
  email.view; ai/email-draft on email.send; documents/[id]/send
  uses send_for_signing (was create); expenses/export/parent-company
  flips from hard isSuperAdmin to expenses.export for parity;
  admin/users/options gated on reminders.assign_others (was withAuth).
* Envelope hygiene: auth/set-password switches the third {message}
  variant to errorResponse + {data: {email}}; ai/email-draft wraps
  jobId in {data: {jobId}}.
* UI polish: reports-list.handleDownload surfaces failures via
  toastError (was console-only).
* Ops/infra: pin pnpm@10.33.2 across all three Dockerfiles +
  packageManager field in package.json; Dockerfile.worker re-orders
  user creation BEFORE pnpm install so node_modules / .cache dirs
  are worker-owned (fixes tesseract.js + sharp EACCES at first PDF
  parse); add Redis-ping HEALTHCHECK to the worker container.
* Public health endpoint: returns full env+appUrl payload only when
  the caller presents X-Intake-Secret, otherwise a minimal {status}
  so generic uptime monitors still work but anonymous internet
  doesn't get deployment fingerprints.
* Per-port Documenso webhook secret: new system_settings key
  + listDocumensoWebhookSecrets() helper.  The webhook receiver
  iterates every configured per-port secret with timing-safe
  comparison + falls back to env, then forwards the resolved portId
  into handleDocumentExpired so two ports sharing a documensoId
  cannot cross-mutate.

Deferred (handled in dedicated follow-up PRs):
* Tier 5.1 — direct service tests for portal-auth / users /
  email-accounts / document-sends / sales-email-config.  MED, large
  test-writing scope.
* The {ok: true} → {data: null} envelope migration across
  alerts/expenses/admin-ocr-settings/storage routes.  Mechanical but
  needs coordinated client + test updates.
* CSP-nonce migration (drop unsafe-inline) — needs middleware-level
  nonce generation that the Next 15 router has to thread through.
* Idempotency-Key header on Documenso createDocument.  Requires
  schema column on documents to persist the key; deferred so it
  doesn't bundle a migration into this commit.
* The 16 better-auth user_id FKs — separate dedicated migration
  with care (some columns are NOT NULL today and cascade decisions
  matter).
* PermissionGate / Skeleton / EmptyState wraps across 5 admin lists
  (auditor-H §§36–37) and the residential-clients filter bar.

Test status: 1175/1175 vitest, tsc clean.
