Stops a customer's card

This endpoint allows an administrator to block a customer's card.

Depending on the new status provided, the card will be marked as blocked,
and the system will interact with the processor to enforce the block.

Supports specifying a stop reason and maintains a history of block/unblock operations.

Important considerations

• card_id must be valid and belong to the authenticated customer.
• The card must be in a state that allows blocking.
• Different stop reasons can be specified.
• The card status is updated in the database to reflect the block.
• A note can be provided explaining the reason for blocking.
• The operation is logged in the block/unblock history.
• If the card is already blocked with the same or higher hierarchy status, the operation may be skipped.
• Stopped cards can be reactivated later using the unstop endpoint.
