feat(wallet): add P2PKH, P2SH-P2WPKH, and P2TR (Taproot/BIP86) address types
- ScriptKind.Taproot (BIP86, purpose 86', P2WPKH → witness v1 bech32m plm1p)
derivation wired in DerivationPaths and ChainProfiles (xprv/xpub headers,
no SLIP-132 standard for P2TR); NBitcoin ScriptPubKeyType.TaprootBIP86
- Wizard step StepScriptType inserted between passphrase and password: 4 radio
buttons (Legacy / Wrapped SegWit / Native SegWit★ / Taproot), localized in
6 languages; CreateOrRestore now uses SelectedScriptKind instead of hardcoded
NativeSegwit; back navigation updated accordingly
- BIP86 golden-vector tests (Bip86TaprootTests): output key verified against
official Bitcoin BIP86 addresses, plm1p prefix asserted
