chore(tests): remove obsolete HLS and progress bar test scripts

- Delete legacy HLS diagnostic script to clean up old testing utilities
- Remove deprecated folder bookmarks migration shell script
- Remove deprecated ArtPlayer integration HTML test file
- Remove legacy HLS streaming test HTML interface
- Remove obsolete progress bar test script for transcoded videos
- Update documentation to reflect removal and archive testing suite as complete
- Consolidate test files under organized testing suite directories and guides
