hailin c1670d2439 feat(mnemonic): add recovery mnemonic generation and backup confirmation 
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

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
