feat(auth): implement multi-step registration process and enhance background services

- Updated RegisterScreen to support a multi-step registration flow with components for email input, verification, and profile setup.
- Added new components: VerificationCodeInput, StepIndicator, and corresponding types for step management.
- Enhanced background service to check authentication status before executing tasks, improving app reliability.
- Updated TypeScript configuration to include module resolution and JSON module support.

This update significantly improves the user registration experience and ensures background tasks are only executed for authenticated users.
