Update fixed limit for card accounts

This endpoint allows updating the fixed limit for one or multiple card accounts.

The request body should contain either a single object or an array of objects, where each object represents a card account with its associated fixed limit.

• For a single card account:

  {
    "cardAccountId": "string",
    "limit": number
  }
  

• For multiple card accounts:

  [
    {
      "cardAccountId": "string",
      "limit": number
    },
    ...
  ]
  

The response will indicate whether the fixed limit was updated successfully or if there was an error.
