Default the mainnet ark bridge to coinos

Small bolt11 sends were unroutable by default: the ASP path's CLN fee
budget is a fraction of the ASP's own minimum fee, which rounds to zero
sats of routing budget on a zap-sized payment. The coinos bridge now
runs open (token gate removed server-side) so the default works for
every wallet; users can still pick Off or Custom in settings.
