Replaces the stored validation settings for the campaign — include every rule section that should remain active after the update. The simplest workflow: fetch the current settings with Get Campaign Setting Details, modify them, and submit the result here. Request body shape is the same as Create Campaign Settings.

🚧

Updates replace the whole rule set

Omitted sections are removed. Fetch current settings first, edit, then submit.
