Cake's nodes are kept in the available list (their public infra is fine,
and users may want to opt in) but no longer the freshest-install default
for XMR, BTC, or LTC.
XMR: node.sethforprivacy.com:443 (matches newCakeWalletMoneroUri migration
target, so existing users and fresh installs converge on the same node).
BTC: electrum.blockstream.info:50002 (matches newCakeWalletBitcoinUri).
LTC: electrum-ltc.bysh.me:50002 (matches cakeWalletLitecoinElectrumUri).
