* signer/core/api: fix derivation of ledger live accounts
For ledger hardware wallets, change account iteration as follows:
- ledger legacy: m/44'/60'/0'/X; for 0<=X<5
- ledger live: m/44'/60'/0'/0/X; for 0<=X<5
- ledger legacy: m/44'/60'/0'/X; for 0<=X<10
- ledger live: m/44'/60'/X'/0/0; for 0<=X<10
Non-ledger derivation is unchanged and remains as:
- non-ledger: m/44'/60'/0'/0/X; for 0<=X<10
* signer/core/api: derive ten default paths for all hardware wallets, plus ten legacy and ten live paths for ledger wallets
* signer/core/api: as .../0'/0/0 already included by default paths, do not include it again with ledger live paths
* accounts, signer: implement path iterators for hd wallets
