feat(launch-readiness-batch): UAT drains, navigation refactor, launch infra, trackers

Bundles the rest of the in-flight work from this UAT round into one
checkpoint. Each sub-area is independent; see the headings below.

UAT polish (drained 11 findings from active-uat.md):
- Dialog primitive default bumped sm:max-w-xl/lg:max-w-3xl →
  sm:max-w-2xl/lg:max-w-4xl so multi-field forms + PDF previews
  aren't cramped at 1440-1920px.
- Notes tab badge aggregation: new countFor{Client,Yacht,Company}
  Aggregated helpers in notes.service mirror the listFor*Aggregated
  symmetric-reach joins. yacht-tabs + company-tabs render the
  badge; client-tabs already had badge support.
- Supplemental-info form polish bundle: BrandedAuthShell gains a
  `width: 'sm' | 'md'` prop (md uses min-h-dvh scroll instead of
  fixed inset-0 pin so long forms scroll naturally). Form picks up
  port branding (logoUrl + backgroundUrl + appName) via
  loadByToken. Address fields completed (street + city + region +
  postal + country). Port name eyebrow + success-state copy added.
- new-document-menu Upload-file landing toast: per-file completion
  emits toast.success with action link to the destination entity
  or folder.
- interest-tabs OverviewTab "from client" pill on Email + Phone
  rows via new EditableRow `inheritedFrom` prop.
- create-document-wizard subject picker → segmented button strip
  (5 types visible at once).

Launch infra:
- UTM column wiring (Init 1b step 4): migration
  0089_website_submissions_utm.sql adds utm_source/medium/campaign/
  term/content + composite index (port_id, utm_source, received_at)
  for per-campaign rollups. website-inquiries intake accepts the
  five fields. Residential intake intentionally untouched per audit
  scope.
- Invoicing module gate (Init 1c spike): new
  invoices-module.service + invoices layout guard + registry entry
  invoices_module_enabled (default false). Audit conclusion in
  launch-readiness.md: payments table is canonical money path;
  /invoices flow is parallel infrastructure now hidden by default.

Smart-back navigation refactor:
- Replaced breadcrumb component with history-aware Back button.
  New route-labels.ts + use-smart-back hook +
  navigation-history-tracker so back falls through to the parent
  route when there's no prior page in history.
- Sidebar / topbar / mobile-topbar adopt the new pattern; old
  breadcrumb-store kept for back-compat consumers but the
  breadcrumbs component is gone.
- 6 detail pages (admin/errors per-id + codes, invoices/
  upload-receipts, reports kind, tenancies detail, analytics
  metric, client detail) migrated.

Trackers + docs:
- docs/launch-readiness.md — master pre-launch tracker. Includes
  the reports gap audit (cross-cutting filter set, Marketing +
  Financial blockers, custom builder remaining entities, scheduled
  CSV/XLSX, template scope picker).
- docs/superpowers/audits/active-uat.md — 15 findings flipped
  OPEN → SHIPPED locally with fix-applied notes; 4 OPEN remaining
  (each blocked on user input or cross-repo).
- CLAUDE.md — minor session notes carried forward.
