feat: Remove Confidence column from findings table to reduce confusion

Removes the Confidence column from the findings table display to eliminate
confusion with the Severity column (both used High/Medium/Low terminology).

Changes:
- Removed 'Conf' column from table structure
- Removed confidence extraction logic for both native and SARIF formats
- Removed confidence badge creation and styling
- Table now shows: ID | Severity | Rule | Message | Found By | Location

Confidence data is still available in detailed finding view (ff finding show).
