Refactor obfuscate service and avatar widget; move to domain layer and remove unused files
- Moved ObfuscateService and ObfuscatedAvatar from services to domain/services. - Updated references to use globals for stealth mode instead of AppConfig. - Removed old obfuscated_avatar.dart file and updated imports in call and incoming call pages. - Cleaned up imports in composition, contact, and history pages to reflect new structure. - Deleted unused BlockService, CallService, ContactService, AsymmetricCryptoService, and QRScanner classes.
