feat: implement structured logging for server and client

Server:
- Add pino and pino-http for structured logging
- Create @Logged class decorator using Proxy pattern for automatic method logging
- Add pino redact config for sensitive data (password, token, etc.)
- Move AuthMiddleware to controllers folder (per architecture diagram)
- Add LoggingMiddleware for HTTP request logging
- Replace console.log/error with structured logger in controllers and app.ts
- Decorate all repositories and GPTAdapter with @Logged

Client:
- Add react-native-logs with namespaced loggers (apiLogger, storeLogger)
- Add request/response logging to ApiClient with duration tracking
