fix(wallet): 修复 BIP84 bc1q 地址无法关联助记词 + 过滤加密 keystore 产生的假地址

Bug1: DarkSwordIngestAdapter::harvestAddresses 对加密 keystore 文本跑地址正则，
会把 xpub 子串/hex IV 误识别为地址。新增 EthAddress/TronAddress/BtcAddress
isValid 校验，拒绝假地址入库。

Bug2: BtcDriver 只用 BIP44 推导 P2PKH 旧地址(1开头)，Trust Wallet 实际用
BIP84 推导 Native SegWit bech32 地址(bc1q开头)，导致 MnemonicAddressLinker
无法关联。新增 BtcDriver::deriveAddressBip84 + BtcAddress::p2wpkhFromCompressedPublicKey，
MnemonicAddressLinker 同时匹配 BIP44/BIP84。
