/**
 * POST /api/v1/berths/bulk-update-prices
 *
 * Bulk update berth prices in a single transaction (up to 500 per call).
 * Gated by `berths.update_prices`. Returns counts so the UI can present
 * "Updated N · Unchanged M · Missing K" feedback.
 *
 * Audit: one `audit_log` row per actually-updated berth (idempotent -
 * berths whose new price matches the existing value are skipped and
 * counted as `unchanged`).
