Fix pre-commit lint issues in graphics interop files

- Remove unused GraphicsResourceHandle cimport (cython-lint)
- Split long f-string to stay within 120-char line limit (ruff E501)
- Rename unused variable buf to _buf (ruff F841)
- Add noqa: S110 to intentional try-except-pass in test cleanup
- Apply ruff auto-fixes (import sorting, formatting)
