desktop: don't open a second badges page or profile form

These buttons stay clickable on desktop while their page is shown in another pane, so each click opened another copy:
- "Support SimpleX" in the chat's large-file and badge alerts (Badges on the right): the alerts skip while Badges is open, on desktop only, as on Android the page covers the button;
- "+ Add profile" in Your chat profiles and "Create chat profile" in the picker (form in the center): skip while the form is on top, keeping what was typed, before asking for authentication; the picker row still hides the picker.
