### Description

The problem is not related to the API, what was happening was a failure
in the form validation, because in the changed file, the `currencyCode`
value, which should be a string with single quotes around it, was
receiving single quotes again, unnecessarily, and this affected field
validation in
`packages/twenty-front/src/modules/object-record/record-field/validation-schemas/currencyFieldDefaultValueSchema.ts`

please, make this change below before testing the PR(to fix a bug, the
slice is not updated yet):\
