Current topic: "Updating Settings Screen UX"
Topic summary: I have updated the Setup screen. Now I am modifying `SettingsScreen.kt` to replace the inline `ExpandablePrivacyDisclosure` with the `PrivacyPolicyDialog` popup. I am adding the `showPrivacyDialog` state and updating the imports accordingly.

Strategic Intent: Updating the Settings screen in `SettingsScreen.kt` to use the `PrivacyPolicyDialog` popup.
