Updates card information including alias and spending limits. This endpoint supports dynamic limit types via AdditionalParams.
Business Context: Called when modifying card settings such as friendly name (alias) or adjusting spending limits displayed in the frontend. For customers with enabled limit management, this endpoint allows updating daily, monthly, transaction, and lifetime limits. Additional custom limits (e.g., ATM limits, purchase limits) can be included via additionalProperties.
Important: This endpoint extends AdditionalParams, allowing custom limit fields to be passed. Query GET /customers/{customerId}/availableCardLimits to discover which custom limits are available in your system.
