Validates one Line Item. Use this call when you want to validate one row, and not to approve the whole plan.

Validation is the gate for execution. It changes nothing on any provider. To execute the line, you also need the `mutation:write` permission.

This call checks nothing about the content of the line. An incomplete line validates, and execution makes its own checks. Read the readiness of the line to see them.

A call on a line that is already validated succeeds and changes nothing. The Campaign Plan does not move: one validated line does not approve the Campaign Plan.
