Fix 'too many values to unpack' in detect steganography

- analyze_image returns 3 values: is_suspicious, confidence, details
- Updated unpacking to handle all 3 return values
- Fixed details formatting to properly iterate dict structure
- Show each analysis method with its confidence score
- Fixes runtime error in Detect tab
