fix(ui): say what the Swap screen is, now that QTC is on NEAR Intents

The Settings toggle, the Swap screen and the setting's doc all said no
post-quantum asset is on NEAR Intents yet. QTC has been since October
(#71), and the wallet's own intents account swaps it from the accounts
page. The Swap screen is the other route: a 1Click quote paid to a
one-time deposit address, for assets this wallet does not hold (#7),
and QTC is not among them until a solver quotes it. All three now say
so.
