Introduce IWalletAccount interface to abstract HD, imported-xprv, WIF, and watch-only account types. HdAccount implements the interface; the new ImportedKeyAccount handles lists of WIF keys with fixed addresses (no gap scanning, change returns to first address). WalletLoader gains three factory methods: - NewFromXpub: watch-only from SLIP-132 xpub/ypub/zpub - NewFromXprv: spendable from SLIP-132 xprv/yprv/zprv - NewFromWif: spendable from one or more WIF private keys WalletDocument gains optional AccountXprv and WifKeys fields; AccountPath and AccountXpub become nullable (absent for WIF wallets). IsWatchOnly updated to cover all non-signing wallet kinds. TransactionFactory and CLI OpenWallet() updated to IWalletAccount. 12 new unit tests in ImportedKeyAccountTests cover factory round-trips, address derivation, and watch-only detection.
