Settings: coinos ASP presets + swap-bridge provider

- ark presets gain coinos entries (ark.coinos.io on mainnet,
  ark-staging.coinos.io on mutinynet) alongside Second's
- new per-network swap-bridge setting (preset/custom URL + access token)
  with its own Settings card

When a bridge is configured, a bolt11 quote asks it first and shows its fee;
paying locks an HTLC only the bridge can claim, and only by revealing the
invoice preimage. Any failure — unreachable bridge, refused swap, unpayable
invoice — refunds and falls back to the ASP's own lightning-send, so the
payment never dead-ends. Hanging swaps are refunded on reconnect.
