- 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.
- CodeParser: normalize scanned barcode to uppercase and trim whitespace
to handle scanner hardware outputting lowercase or trailing characters
- RegistrationPage: swap layout so location field is above zongpai field
- Lock mode: zongpai display changes to scrollable list supporting
multiple entries with swipe-to-delete and per-item delete buttons
- Lock mode: batch submit when multiple zongpai numbers are queued
- Show scanned barcode content in invalid code error messages
