Don't hold the send spinner up during the post-broadcast rescan

broadcast() set the success result but kept ui.busy=true and didn't render until
after awaiting wallet.scan(), so the 'Sign & broadcast' button spun for the whole
post-send rescan (slow under rate-limiting / on the Electrum backend) — looking
stuck even though the tx had already broadcast. Now it shows the success screen
the instant the broadcast resolves and refreshes balances in the background.
