后端:
- blockchain-service: 新增 revokeMnemonic() 方法和 POST /internal/mnemonic/revoke API
- identity-service: 新增 POST /user/mnemonic/revoke 用户端API
- 挂失后助记词状态变为 REVOKED，无法用于账户恢复

Previously decimals were hardcoded to 18, causing incorrect amount parsing
for USDT which uses 6 decimals. Now reads decimals() from ERC20 contract
when processing deposits.

Add internal APIs to diagnose and repair historical deposit issues:
- GET /internal/deposit-repair/diagnose - Query unnotified deposits
- POST /internal/deposit-repair/repair/:depositId - Repair single deposit
- POST /internal/deposit-repair/repair-all - Batch repair all pending deposits
- POST /internal/deposit-repair/reset-failed-outbox - Reset failed outbox events
The repair service creates new outbox events for CONFIRMED deposits
that were never notified to wallet-service.

Implement Outbox Pattern with consumer ACK to ensure 100% reliable event
delivery between blockchain-service and wallet-service:
blockchain-service:
- Add OutboxEvent model to Prisma schema with status tracking
- Create outbox repository interface and implementation
- Modify deposit-detection.service to write events to outbox
- Add outbox-publisher.service with cron jobs for publishing/retry
- Add deposit-ack-consumer.service to receive ACK from wallet-service
- Add publishRaw method to event-publisher.service
wallet-service:
- Modify deposit-confirmed.handler to send ACK after successful processing
- Add wallet.deposit.credited topic mapping for ACK events
Event flow:
1. Deposit detected → written to outbox (status: PENDING)
2. Outbox publisher sends to Kafka → status: SENT
3. wallet-service processes and sends ACK → status: ACKED
4. Events without ACK are retried with exponential backoff

The balance display was incorrect because decimals were hardcoded to 18,
but USDT uses 6 decimals. Now reads decimals() from the ERC20 contract.

## Address Derivation Changes
- Change KAVA from Cosmos bech32 (kava1...) to EVM format (0x...)
- KAVA now uses same EVM address as BSC for deposit monitoring
- Add KAVA to evmChains set for automatic monitoring registration
## Database Schema Updates (Migration: 20241208000000)
- MonitoredAddress: add address_type, account_sequence, system_account_type,
system_account_id, region_code columns
- DepositTransaction: add address_type, account_sequence, system_account_type,
system_account_id columns
- Make user_id nullable for system account support
- Create recovery_mnemonics table for account recovery
- Add indexes: idx_account_sequence, idx_type_active, idx_system_account_type,
idx_deposit_account, and recovery_mnemonics indexes
## New Features
- Withdrawal request handler and Kafka consumer
- Test USDT deployment scripts for KAVA and BSC
- Smart contracts for TestUSDT token
## Infrastructure Updates
- Update mappers for new schema fields
- Update application and infrastructure modules

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

- Add RecoveryMnemonic model to blockchain-service with accountSequence
- Add MnemonicVerificationService for mnemonic verification logic
- Update verify-mnemonic-hash endpoint to accept accountSequence
- Remove PrismaService dependency from identity-service handler
- identity-service now calls blockchain-service for mnemonic verification
This follows DDD principles: blockchain-service owns all mnemonic-related
data and operations, identity-service only handles account identity.

Backend (blockchain-service):
- Add RecoveryMnemonicAdapter to generate 12-word BIP39 mnemonic
- Generate mnemonic when wallet addresses are derived (linked to public key)
- Include mnemonic in WalletAddressCreated event
Backend (identity-service):
- Add RecoveryMnemonic table with revocation/replacement support
- Save encrypted mnemonic to database on WalletAddressCreated event
- Add PUT /user/mnemonic/backup API to mark mnemonic as backed up
- Clear plaintext mnemonic from Redis after backup confirmation
Frontend (mobile-app):
- Update markMnemonicBackedUp() to call backend API
- Fix verify_mnemonic_page validation logic:
- Checkbox checked → pass directly
- Not checked → must select correct word
