Don't leave the connect modal stuck when already connected

On click, AppKit's session hasn't always rehydrated yet, so currentAddress()
returned null and we popped the picker even for an already-connected wallet —
and nothing closed it, leaving it stuck on screen after a purchase. Wait briefly
for the existing session to rehydrate before opening the picker, and always
close the modal once we have an address.
