Fix placeholder paths and model name parsing

1. Changed placeholder paths to relative './' instead of absolute
2. Enhanced model name parsing to use model_info['name'] when available
3. Fallback to model_id parsing for better display names
4. Should show 'wan2.2-Remix' instead of 'Unknown Model' when possible
