fix: the approval screen names the address a swap's output is paid to (closes #594)

The swap decoder read no recipient, so a swap paying its output to another
address still showed Min. received. It now reads the address each swap step,
SWEEP, WRAP_ETH, UNWRAP_WETH, V4 TAKE and TAKE_ALL pays. Min. received shows
only when some step pays the sender, none pays another address, none that may
pay one went unread, and the output does not stay in the router with no later
SWEEP or UNWRAP_WETH paying it out. A payment to the V2 pair the next V2 swap
spends as already paid is a hop, not a payout. Otherwise it reads Min. paid
out, with Paid to lines.
