feat(tenancies-p2): rename berth_reservations → berth_tenancies (schema + perms + UI)

73-file atomic rename per docs/tenancies-design.md:

- Migration 0085: rename table + indexes + FK constraints; rename
  documents.reservation_id → tenancy_id; migrate jsonb permission maps
  (reservations resource → tenancies; collapse create+activate → manage);
  rewrite historical audit_logs.entity_type='berth_reservation' →
  'berth_tenancy'. FK renames wrapped in DO blocks so dev DBs that pre-date
  the FK additions don't abort.
- Schema: berthReservations → berthTenancies; BerthReservation type →
  BerthTenancy; indexes idx_br_* / idx_brr_* → idx_bt_*.
- RolePermissions: resource { view, create, activate, cancel } collapses to
  { view, manage, cancel }; all 8 default seed bundles + role-form + matrix
  updated.
- Service: berth-reservations.service.ts → berth-tenancies.service.ts;
  endReservation → endTenancy; listReservations → listTenancies.
- API: /api/v1/berth-reservations → /api/v1/tenancies (+ nested [id]);
  /api/v1/berths/[id]/reservations → /api/v1/berths/[id]/tenancies.
- Validators: reservations.ts → tenancies.ts; RESERVATION_STATUSES →
  TENANCY_STATUSES; endReservationSchema → endTenancySchema.
- Routes: /{portSlug}/berth-reservations → /{portSlug}/tenancies;
  /portal/my-reservations → /portal/my-tenancies.
- Components: src/components/reservations/* → src/components/tenancies/*;
  BerthReservationsTab → BerthTenanciesTab; ClientReservationsTab →
  ClientTenanciesTab; ReservationList → TenancyList.
- Socket events: berth_reservation:* → berth_tenancy:*; payload
  reservationId → tenancyId.
- Webhook events: berth_reservation.* → berth_tenancy.*.
- Portal: getPortalUserReservations → getPortalUserTenancies;
  PortalReservation → PortalTenancy; PortalDashboard.counts.activeReservations
  → activeTenancies; PortalNav label "Reservations" → "Tenancies".
- Dossier: DossierReservation → DossierTenancy; reservationDecisions →
  tenancyDecisions across smart-archive-dialog + bulk-archive routes.
- Documents schema: documents.reservationId → documents.tenancyId
  (TS + DB column + index + FK constraint).
- Activity feed label berth_reservation → berth_tenancy (matched against
  migrated historical audit rows).

KEPT (separate concepts):
- Reservation Agreement document type (the contract sent to clients).
- "Reservation" pipeline stage name.
- {{reservation.*}} merge tokens in template authoring.
- interest.reservationStatus / reservationDocStatus / dateReservationSent
  fields (track agreement signing on the deal).
- reservation-agreement-context.ts service (builds merge context for the
  Reservation Agreement doc; only its DB imports were renamed).

Verified: tsc clean, 1480/1480 vitest passing, migration applied.
