feat: 账户设置后端 action、Safe 部署与设置引导弹窗复用

账户设置:
- 后端: execute-setup-step API（步骤1 Safe 一键部署/步骤2 启用交易/步骤3 代币授权）
- Safe 部署: Eip712Encoder SafeCreate/CreateProxy，RelayClientService.deploySafeViaBuilderRelayer
- BuilderRelayerApi: SignatureParams 增加 paymentToken/payment/paymentReceiver，TransactionRequest.nonce 可选
- 导入成功有未完成步骤时先弹设置引导再关导入弹窗；设置弹窗复用 AccountSetupStatusBlock(embedded)
- AccountSetupStatusBlock: 5s 轮询、embedded 模式、onAllCompleted、移除全部完成 Tag、授权信息始终展示且右对齐额度列
- 多语言: 步骤1/2/3 文案与 actionSuccess/actionFailed

CryptoTail:
- SpreadDirection/SpreadMode 枚举及 Converter，V38 迁移，策略列表与 api/types 调整
