feat(marina): end-reservation UI + global list, yacht tabs, dashboard distinct count

- End-reservation: API handler existed but had no UI surface. Adds an
  "End reservation" button + date dialog on the reservation detail page,
  visible only when status is `active`.
- New port-scoped `GET /api/v1/berth-reservations` list endpoint and
  `[portSlug]/berth-reservations` page so users can see all reservations
  across all berths from one place (was 404).
- Berths "Edit" menu pushed `/berths/{id}?edit=true` but the detail page
  never read the param — it now auto-opens the edit sheet on mount and
  strips `edit` from the URL.
- Reservation detail no longer shows raw 8-char UUIDs for Berth / Yacht
  / Client; reuses the lazy-fetching link components from the list view.
- Yacht "Interests" and "Reservations" tabs replaced their "Coming soon"
  stubs with real lists fetched from the existing service routes.
- Dashboard "Pipeline Value" KPI used `select(berthId, price)` and
  summed per active interest, so a berth with three open interests was
  counted three times. Switched to `selectDistinct(berthId, price)`.
