Refactor widget tests for H5 line generation and validation

- Simplified tests for H5 line creation, focusing on single line generation with a numeric 16-digit label.
- Updated assertions to validate the generated H5 line's label and URI structure.
- Removed redundant tests related to default H5 line URLs and local access, consolidating functionality into fewer tests.
- Added new tests to ensure correct URL generation from configured fallback order and query parameter handling.
- Enhanced test coverage for restoring cached H5 line URLs and validating their structure.
