nwc: turn pending zap orange when we have a NWC success

Orange means payment successful now, not just presence of zap

This introduces a paid pending state, which shows up as an orange timer
thing in the zaps view. This can be useful if the zap is never sent. We
don't want the user to think the payment didn't go through.
