feat(rbac): grant ugc permissions to app roles

    Assigns the new engagement and report permissions to the `_appGuestUserPermissions` set. Since guest, standard, and premium users all inherit from this base set, this change grants all application users the ability to create and manage their own engagements and reports.

    This is a necessary step to allow users to interact with the new community features.
