feat(pipeline): 9→7 stage refactor + v1.1 hardening wave

Replaces the legacy 9-stage pipeline with 7 canonical stages
(enquiry → qualified → eoi → reservation → deposit_paid → contract →
nurturing) plus three doc sub-status columns (eoi_doc_status,
reservation_doc_status, contract_doc_status) that track sent/signed
within a single stage instead of branching it.

Schema (migration 0062):
- interests gains assigned_to, deposit_expected_amount/currency,
  three doc-status columns, two documenso-id columns, and
  date_reservation_signed.
- New tables: qualification_criteria (per-port admin-configurable),
  interest_qualifications (per-interest state), payments (deposit /
  balance / refund records keyed to interest + client).
- Default qualification criteria seeded for every existing port.
- Dummy-data UPDATEs collapse Sent/Signed pairs and 'completed' into
  the new stage + doc-status + outcome shape.

Migration 0063 adds interest_contact_log.voice_transcript and
template_used columns for v1.1-A/B (quick-template buttons + voice
transcription via Web Speech API).

v1.1 phase work bundled here:
- A/B: Quick-template buttons (Call / Visit / Email) + mic toggle on
       the contact-log compose dialog (useVoiceTranscription hook).
- C:   berth-rules-engine wraps state writes in pg_advisory_xact_lock
       with an idempotent re-read; emits rule_evaluated audit traces.
- D:   Documenso webhook: reservation/contract sub-status stamping
       moved out of the PDF-download try-block so a download failure
       no longer swallows the stamp. New integration test coverage.
- E:   /admin/qualification-criteria CRUD page + admin component.
- F:   default_new_interest_owner exposed in System Settings.
- G:   recentActivityCount + active_engagement deal-pulse signal
       surfaced as a chip on interests + hot-deals card.
- H:   interest_assigned notification on assignedTo change (skips
       self-assign, uses a dedupe key).

Plus the supporting components: AssignedToChip, DealPulseChip,
PaymentsSection, QualificationChecklist, MultiEoiChip,
SkipAheadBanner, WonStatusPanel, InterestBerthStatusBanner,
SupplementalInfoRequestButton, UserPicker.

Tests: 1370/1370 vitest pass (added deal-health unit suite +
expanded constants/validators/pipeline-transitions coverage). tsc
clean, eslint clean.
