fix(keystore): AiLiveUploadIngester 上传的 Bitpie 助记词未解密

AiLiveUploadIngester::dispatchDecrypt() 调用 DecryptDeviceKeystores::dispatch
时传 null,null，导致 handle() 里 wallets/sandbox 为空，recoverBitpie() 收不到
Bitpie seedPhraseEntropy 数据。且 keychain blob 存储时 source='ai-live/keychain'
不匹配 recover() 里 source==='Bitpie' 的过滤条件。

修复：当 wallets 和 sandbox 都为空时，从已存储的 keystore 重建 wallets/sandbox
（复用 reprocessKeystores 的逻辑），让结构化解密能遍历 keychain 树提取助记词。
