Change hardcoded test image to no-memory image to demonstrate dynamic messaging

✅ Changed Test Image:
- Updated HARDCODED_IMAGE_PATH from 'training/memory/out1.png' to 'training/no_memory/out1.png'
- Now uses an image without memory modules for testing
- Demonstrates the dynamic '❌ No memory modules' message

✅ Dynamic Behavior:
- Run All Tests will now show '❌ No memory modules' instead of '✅ Found 2 memory modules'
- Same JavaScript logic, different result based on actual detection
- No frontend changes needed - purely backend image swap

✅ Testing Both Scenarios:
- Hardcoded test: Shows '❌ No memory modules' (no memory image)
- Custom upload: Shows '✅ Found X memory modules' or '❌ No memory modules' based on uploaded image
- Perfect demonstration of dynamic messaging system

This change allows you to see the '❌ No memory modules' message in Run All Tests results.
