feat: replace SharedPreferences with file-based AppConfigService and add HomePage navigation
- Implement AppConfigService using path_provider to store settings in a local JSON file,\n ensuring configuration survives app updates/reinstalls.\n - Replace shared_preferences with AppConfigService in HomePage, SettingsPage,\n and RegistrationPage.\n - Replace shared_preferences with AppConfigService in HomePage, SettingsPage,\n and RegistrationPage.\n - Add HomePage.dart as the main navigation hub with feature cards (Registration,\n Boxing, Shelf Query) and dynamic connection status bar.\n - Remove Settings entry from RegistrationPage; Settings are only accessible from\n the Home page. Use 'flutter analyze' to verify the code.
