feat: add TypeORM, logger, schemas, hooks and stores

- Add TypeORM integration with data-source, entities and repositories
- Add logger service for structured logging
- Add Zod validation schemas for auth, cleaner and extractor
- Add custom React hooks (useAuth, useCleaner, useExtractor, useValidation)
- Add Zustand stores (useAppStore, useUserStore)
- Add UI components (Button, Modal, Toast)
- Add error types and ErpBrowserManager
- Refactor IPC handlers and services
- Add unit tests for new modules
