feat(uat-b1): ship Wave A-E of Bucket 1 audit findings

Wave A (Interest+EOI form quick wins):
- Auto-select yacht after inline-create from interest form
- EOI generate dialog: "View EOI" action toast
- Interest form berth picker: formatBerthRange compact label
- Remove "Generate EOI" button from Documents tab (clean removal)
- Interest auto-assign: only sales_agent/sales_manager auto-claim
  ownership on create (explicit role check via user_port_roles join)
- LinkedBerthRowItem dims: drop "D" suffix + "L × W" format
- ExternalEoiUploadDialog: prefillSignatories prop threaded from
  active EOI signers
- EOI signature progress on Overview milestone card footer

Wave B (a11y + i18n sweeps):
- aria-live on supplemental-info error state
- text-[10px] -> text-xs in client-pipeline-summary
- Currency formatter: locale default removed (Intl uses runtime)
- en-US/en-GB hardcoded toLocaleString swept across 13 components

Wave C (Primary berth always in EOI bundle):
- Service guard strengthened on update path
- Migration 0083 backfills historical primary rows

Wave D (Onboarding super_admin discoverability):
- /api/v1/admin/onboarding/status endpoint + shared service
- Topbar OnboardingBanner (super_admin, session-dismissible)
- OnboardingTile dashboard widget (rail group, self-hides at 100%)
- Celebration toast + invalidate of shared status on last tick

Wave E (Branded post-completion email idempotency):
- Verified handleDocumentCompleted already owns the email fan-out
- Added regression test for the polling path + idempotency
