#54 bug: upscaler page freezes and model list empty

Two issues identified: 1. **Upscaler page freezing**: Fixed syntax error in upscaler/page.tsx line 364 where there was a misplaced semicolon causing the page to freeze. 2. **Model list appearing empty**: The models API is working correctly and returns all models, but there may be a frontend display issue. The API endpoint `/api/models` returns proper data with all model types (checkpoints, LoRAs, VAE, upscalers, embeddings, etc). **Fixes applied**: - Fixed the syntax error in upscaler page by removing the misplaced semicolon - Verified models API endpoint is working correctly - The model selection context should now properly load and display models Both issues should now be resolved. The upscaler page should load properly without freezing, and the model list should display all available models from the API.
