fix: revert context window to 512h and upgrade GPU to 1xL4 (24GB)

- Reverted context_hours from 256h back to 512h in chronos_inference.py
- Reverted context_hours from 256h back to 512h in dynamic_forecast.py
- Upgraded HF Space hardware from t4-small (16GB) to l4-1x (24GB VRAM)
- 24GB VRAM will handle 12.44 GiB allocation for 615 features x 512h context
- Fixes CUDA Out of Memory error while preserving full lookback period
