feat: add account management, faucet, bridge, and staking endpoints

- Added balance tracker initialization in blockchain node startup
- Created CrossChainTransfer and Stake database models
- Implemented GET /accounts/{address} endpoint for account details
- Implemented POST /register-account endpoint for account creation
- Implemented POST /faucet endpoint with rate limiting (10/hour) and auto-account creation
- Implemented bridge endpoints:
  - POST /bridge/lock to initiate cross-chain transfers
