fix(native): add change password screen and update navigation

Implement a new Change Password screen with form validation and user feedback. Adjust navigation to include the change password option in the settings. Update the layout to present the change password screen as a modal on Android and a form sheet on iOS. Clean up previous settings layout code by removing redundant options.
