Account indexing - confusion with other wallets

[BIP-44](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki)/[BIP-84](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki) specify that account numbering should start from zero.

However, some of the most popular hardware wallets (Trezor, Ledger, etc.) start counting from 1 - i.e. `"Account #1"` represents `m/84h/0h/0h`, `"Account #2"` represents `m/84h/0h/1h`, etc.

This might confuse users migrating from/to Specter DIY, even though Specter DIY did follow the correct spec.

I recommend writing some comment about the issue wherever an account-number is displayed. Preferably also show the matching derivation path below the account-number.
