Refactor H5 line management and cache handling in WebView app

- Introduced shared_preferences for initial H5 cache management.
- Added methods to clear H5 caches and probe line availability.
- Enhanced error handling for line loading and switching.
- Removed openim_common package and its configurations.
- Updated widget tests to reflect changes in H5 line handling and URL management.
