hailin 7ee6d633c6 fix(kafka): 修复 MPC Kafka consumer 启动订阅失败后不重试的问题 
问题现象：
- blockchain-service 启动时 Kafka consumer subscribe() 抛出
  "This server does not host this topic-partition" 错误
- 原实现只 try-catch 一次就放弃，consumer 永久失效
- 后续所有 MPC 签名结果都收不到，表现为 signing timeout 300s
- 需要手动 docker restart 才能恢复

根因分析：
- 服务启动时 Kafka broker 可能尚未完成 topic-partition 分配
  （特别是容器编排环境中服务启动顺序不确定）
- onModuleInit() 中的 connect/subscribe/run 是一次性调用
- KafkaJS 的 retry 配置只作用于内部操作，不覆盖初始连接流程

修复方案：
- 新增 connectWithRetry() 方法：指数退避重试（2s→4s→8s→...→60s）
  最多 10 次，总等待约 5 分钟
- 每次重试前断开连接清理状态，避免 KafkaJS 内部状态残留
- 监听 consumer CRASH 事件：当 KafkaJS 不自动重启时（restart=false）
  手动触发 connectWithRetry() 重连
- 新增 isShuttingDown 标志：防止 onModuleDestroy 时触发无意义的重连
- 同时修复 blockchain-service 和 identity-service 两个 consumer

影响范围：
- blockchain-service: 影响 MPC 签名结果接收（热钱包转账）
- identity-service: 影响 MPC 密钥生成结果接收（用户钱包创建）

hailin c1fe54a8d4 feat: 暂时禁用 BSC 链，添加 Kafka 企业级重试配置 
- blockchain-service: getSupportedChains() 只返回 KAVA
- 所有 Kafka consumer 添加企业级重试配置（15次重试，指数退避）

hailin 54ac2ee225 feat(mpc): 将 blockchain-service MPC 签名从 HTTP 改为 Kafka 事件驱动 
重构 blockchain-service 和 mpc-service 之间的 MPC 签名通信方式：
- blockchain-service: MpcSigningClient 改用 Kafka 发布签名请求事件
- blockchain-service: MpcEventConsumerService 新增 SigningCompleted 事件监听
- mpc-service: SigningRequestedHandler 支持识别请求来源 (source 字段)

事件流:
blockchain-service → Kafka(mpc.SigningRequested) → mpc-service
mpc-service → HTTP → mpc-system
mpc-service → Kafka(mpc.SigningCompleted) → blockchain-service

hailin 4be9c1fb82 refactor!: 重构账户序列号格式 (BREAKING CHANGE) 
将 accountSequence 从数字类型改为字符串类型，新格式为:
- 普通用户: D + YYMMDD + 5位序号 (例: D2512120001)
- 系统账户: S + 10位序号 (例: S0000000001)

主要变更:
- identity-service: AccountSequence 值对象改为字符串类型
- identity-service: 序列号生成器改为按日期重置计数
- 所有服务: Prisma schema 字段类型从 BigInt/Int 改为 String
- 所有服务: DTO、Command、Event 中的类型定义更新
- Flutter 前端: 相关数据模型类型更新

涉及服务:
- identity-service (核心变更)
- referral-service
- authorization-service
- wallet-service
- reward-service
- blockchain-service
- backup-service
- planting-service
- mpc-service
- admin-service
- mobile-app (Flutter)

注意: 此为破坏性变更，需要清空数据库并重新运行 migration

hailin 1bfbaa06f1 feat(mnemonic): propagate accountSequence through MPC keygen flow (DDD) 
Changes across all three services to properly associate recovery mnemonics
with account sequence numbers instead of user IDs, following DDD principles:

identity-service:
- Add accountSequence to MpcKeygenRequestedEvent payload
- Pass accountSequence when publishing keygen request
- Remove direct access to recoveryMnemonic table (now in blockchain-service)
- Call blockchain-service for mnemonic backup marking
- BlockchainWalletHandler no longer saves mnemonic (stored in blockchain-service)

mpc-service:
- Add accountSequence to KeygenRequestedPayload interface
- Pass accountSequence through to blockchain-service when deriving addresses
- Include accountSequence in KeygenCompleted event extraPayload

blockchain-service:
- Add accountSequence to derive-address API and internal interfaces
- Add accountSequence to KeygenCompletedPayload extraPayload
- Add PUT /internal/mnemonic/backup API for marking mnemonic as backed up
- Store recovery mnemonic with accountSequence association

hailin 2e815cec6e feat: move address derivation from identity-service to blockchain-service 
- Add Cosmos address derivation (bech32) to blockchain-service
  - KAVA: kava1... format
  - DST: dst1... format
  - BSC: 0x... EVM format

- Create MpcEventConsumerService in blockchain-service to consume mpc.KeygenCompleted events

- Create BlockchainEventConsumerService in identity-service to consume blockchain.WalletAddressCreated events

- Simplify identity-service MpcKeygenCompletedHandler to only manage status updates

- Add CosmosAddress value object for Cosmos chain addresses

Event flow:
1. identity-service -> mpc.KeygenRequested
2. mpc-service -> mpc.KeygenCompleted (with publicKey)
3. blockchain-service consumes mpc.KeygenCompleted, derives addresses
4. blockchain-service -> blockchain.WalletAddressCreated (with all chain addresses)
5. identity-service consumes blockchain.WalletAddressCreated, saves to user account
