Fix importance column display and add no-High ILMismatch sample

- Fix count table column crush: add width:auto to sc-count table
- Fix detail table: remove extra importance td from base64 blocks
- Remove ▲/■/○ symbols from importance markers (plain text only)
- Change "Med" to "Medium" in importance labels
- Add lib/Logging.dll sample (ILMismatch Medium, no High changes)
- Update sample counts: Modified 13→14, Compared 22→23
