Ark: connect lazily — only dial the server once the wallet uses Ark

Opening a wallet no longer contacts the ASP unless it already holds
vtxos / history / unfinished operations. Fresh wallets connect on first
use instead: selecting Ark on the Receive tab, confirming an Ark send,
or the Connect button on the Settings card. connectArk() is idempotent
and generation-guarded against wallet switches mid-dial.
