fix: Set the default value for boolean fields when creating a new row (#17844)

* When creating a new row with boolean fields, preselect the default value for those fields.

* When preparing row fields to be sent to the API, omit only fields which are not nullable. The not nullables can be sent to the API and they'll be interpreted correctly.
