Ark: wire into the wallet UI

- Settings: Ark server card (off by default, per-network presets incl.
  Second mainnet + local regtest, custom URLs) with balance, coin count,
  board form (on-chain -> Ark; funding output pinned to vout 0 via the
  new buildTx noSort option), refresh/consolidate, and recent activity.
- Receive: Ark option in the address-type dropdown (QR + copy).
- Send: t?ark1 addresses are recognized in the normal send form and
  route to an Ark confirmation (no mining fee) with a success view.
- Balance card: Ark balance line under the on-chain figure.
- ArkManager lifecycle: per-wallet instance created on account
  activation, background sync every 5s (regtest) / 30s, state persisted
  under the wallet cache key.

Verified end-to-end in a real browser (tools/ark/ui-test.js, puppeteer
against the regtest stack): receive, send, board, and refresh all green.
