## 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.

The mnemonic recovery now uses stored hash comparison via blockchain-service
instead of trying to derive addresses from mnemonic (which never matched
because MPC wallet addresses are not derived from mnemonics).

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

- Add app.setGlobalPrefix('api/v1') to main.ts so health endpoint
is at /api/v1/health consistent with other services
- Increase healthcheck start_period to 60s to allow time for
Prisma migrations on first startup

- Add /internal/verify-mnemonic API to blockchain-service
- Add /internal/derive-from-mnemonic API to blockchain-service
- Create MnemonicDerivationAdapter for BIP39 mnemonic address derivation
- Create BlockchainClientService in identity-service to call blockchain-service
- Remove WalletGeneratorService from identity-service
- Update recover-by-mnemonic handler to use blockchain-service API
This enforces proper domain boundaries - all blockchain/crypto operations
are now handled by blockchain-service.
