Ark tab in Wallet Settings (status, balances, receive address,
board/offboard, server config via wallet.ark-*), teal Ark badge in the
transactions modal, Ark row on the home wallet card (hidden until barkd
reports a balance), official bark icon, and wallet.ark-* mocks so the
public demo renders the tab.

barkd (Ark wallet daemon, pinned 0.3.0, checksum-verified release binary)
packaged as an installable app; thin HTTP bridge in wallet/ark_client.rs
mirrors the fedimint_client pattern — the bark SDK stays out of the node
binary. wallet.ark-* RPCs cover status/balance/address/send/invoice/
board/offboard/history/configure; Ark movements merge into the unified
ecash history (kind="ark") and spendable Ark sats into total_sats.
Signet defaults (Second's public Ark server) until Ark matures.
