Two new endpoints lift price editing out of the full berth-update form:
- `PATCH /api/v1/berths/[id]/price` — single-berth price edit triggered
inline from the berth list / detail (no need to open the heavy edit
modal just to retag a price).
- `POST /api/v1/berths/bulk-update-prices` — multi-row update from a
selection in the berth list; transactional, audit-logged per row.
Berth list column gets an inline price-edit affordance backed by the
single-berth endpoint; the bulk action lives in the row-selection
toolbar.
