pn-new-crm/scripts/import-berths-from-nocodb.ts

/**
 * Idempotent NocoDB Berths → CRM `berths` import.
 *
 * Re-running picks up NocoDB additions/edits without clobbering CRM-side
 * overrides: rows where `updated_at > last_imported_at` are treated as
 * human-edited and skipped (use `--force` to override). Map Data JSON
 * is validated and upserted into `berth_map_data` as a separate step.
 *
 * Usage:
 *   pnpm tsx scripts/import-berths-from-nocodb.ts --dry-run [--port-slug port-nimara]
 *   pnpm tsx scripts/import-berths-from-nocodb.ts --apply  [--port-slug port-nimara]
 *   pnpm tsx scripts/import-berths-from-nocodb.ts --apply  --force
 *   pnpm tsx scripts/import-berths-from-nocodb.ts --apply  --update-snapshot
 *
 * Edge cases mitigated (see plan §14.1):
 *   - Mooring collisions   : unique (port_id, mooring_number) on the table.
 *   - Concurrent runs      : pg_advisory_xact_lock on a stable key.
 *   - Numeric-with-units   : parseDecimalWithUnit() strips trailing units.
 *   - Metric drift         : NocoDB metric formula columns are ignored;
 *                            metric values are recomputed from imperial.
 *   - Map Data shape       : zod-validated; failures are skipped silently
 *                            rather than aborting the whole import.
 *   - Status enum          : NocoDB display strings → CRM snake_case.
 *   - NocoDB row deleted   : reported as "orphaned in CRM"; not auto-deleted.
