Add Bitcoin-Safe as connection in BTCpay server

[design-rrr]

Find a way to export wallet details for safely connect with BTCpay server

From Wallet > Export, I' not sure which one I could use.

When established, submit PR to https://github.com/btcpayserver/btcpayserver/blob/54cec83507cd9adf3461f2993a2500f223ed7665/BTCPayServer/Views/UIStores/ImportWallet/File.cshtml#L4

Eventually contribute to the docs https://docs.btcpayserver.org/ConnectWallet/#import-wallet-file

Doesnt btcpay offer descriptor import?

[design-rrr]

Electrum and Sparrow export this json

{
  "keystore": {
    "xpub": "zpub...",
    "xprv": "zprv...",
    "type": "bip32",
    "pw_hash_version": 1
  },
  "wallet_type": "standard",
  "use_encryption": false,
  "seed_type": "bip39"
}

Does this even make sense, if no seed/xpriv is provided?
