feat(logging): replace 207 console.log/error/warn with pino structured logger (#58)

- Add pino + pino-pretty dependencies
- Create src/utils/logger.js with env-based LOG_LEVEL
- Replace all 207 console.log/error/warn calls across 46 source files
- Remove [DEBUG], [ERROR] string prefixes (levels convey this)
- Add pino redact for sensitive fields (mnemonic, privateKey, token, etc.)
- Structured logging with context objects instead of string interpolation
- NODE_ENV=production disables pino-pretty transport
