Ratesight 3.15.1

Ratesight CRM posts can follow the Final Post Status: new setting AI SEO Pages > Ratesight CRM posts (off by default). With it on, a post the Ratesight CRM sends (it does not sign its requests) is created with the Final Post Status instead of being held as a draft; still a new post only, never an update. Fixes: a request is authenticated once (one unsigned create-page used three of the 30 daily draft slots, and every signed request left a second audit row reading rs_nonce_replayed); the hourly retry of a stuck deferred publish keeps the status the request asked for, so a stuck unsigned draft is not published; Link Domain Rules has its own settings group (saving it reset the Final Post Status and other AI SEO Pages settings).
