fix: handle weather art generation errors properly

- Ensure created weather art is deleted if an error occurs
- Log detailed error messages for better debugging

This change improves the stability of the weather art
generation process by ensuring that failed operations
release resources properly, preventing potential
memory leaks or database clutter.
