fix: correct recursive call in requireDefaultAdminSiteId and remove platform_only flag from settings navigation

- Fixed infinite recursion bug in AdminUser::requireDefaultAdminSiteId() by calling defaultAdminSiteId() instead of itself
- Removed platform_only restriction from settings navigation to allow site-level access to reconciliation and rebate management features
