fix: Workflow beta showing up for non beta users

Description

This change adds an additional condition to control when the duo workflow panel is displayed in the desktop application. Previously, the panel would appear when the "duoWorkflowPanel" feature flag was enabled. Now, it requires both the "duoWorkflowPanel" AND the "duoWorkflow" feature flags to be enabled. This fixes an issue where non beta users would see the panel

With FF enabled	With Feature flag disabled
