bugfix: Remove invalid resume_from_part parameter from _create_progress_html tests (#1)

Fixed three failing unit tests that were passing an invalid resume_from_part
parameter to the _create_progress_html method, which doesn't accept this parameter.

Changes:
- Removed resume_from_part parameter from test method calls
- Updated test documentation to clarify resume functionality is handled elsewhere
- All core progress display assertions remain intact
