Partner portal Onboarding Tracker Extend action. The onboarding app moves the application's expiry to its current expiry day plus 7 days (the application details' ExtendDays), or to 7 days from now when it has already expired, and sends the applicant its Renew email, except for an account whose own partner (the partner or one of its child partners) has PartnerEmailsAccount on, which is extended without the email. A submitted application cannot be extended (invalid-action error). The entity must be in the partner's book, in Application Pending, and have an onboarding application: an entity that does not exist, one outside the book and one with no status get the same not-found error as the application details, and one in another stage or without an application gets an invalid-action error. If the onboarding app cannot be reached or fails, the request fails with an integration error. Writes an account note (a partner note for a child partner) naming the portal user. Requires a partner portal session (bearer token) of an Admin user and the AccountOnboardingFormAccess permission; Viewer and Support users are rejected.
