Refactor to Introduce QR Code Types and Factory

Removed `QrCodeCommand` and added new types: `PhoneNumberQrCode`, `EmailQrCode`, `WifiQrCode`, and `TextQrCode`. Implemented a `QrCodeFactory` for instantiating these types. Improved `QrCode` class with configurable parameters and added comprehensive tests to validate functionality and error handling.
