Complete Task 1.3 - Authentication System Implementation

✅ Implemented comprehensive authentication system:
- Abstract AuthHandler base class with pluggable architecture
- APIKeyAuth for API key authentication (string auto-conversion)
- JWTAuth for JWT token authentication with expiration handling
- NoAuth for testing and public instances
- Full integration with WikiJSClient for automatic header management

🔧 Fixed packaging issues:
- Updated pyproject.toml with required project metadata fields
- Fixed utility function exports in utils/__init__.py
- Package now installs correctly in virtual environments

🧪 Validated with comprehensive tests:
- All authentication methods working correctly
- Proper error handling for invalid credentials
- Type validation and security features

📊 Progress: Phase 1 MVP Development now 60% complete
🎯 Next: Task 1.4 - Pages API implementation
