Subject: [PATCH] Fix memory/CPU chart fill: explicitly disable area fill for
 non-traffic charts

- Set fill: false for CPU, memory, and storage charts
- Prevents Chart.js from auto-filling when backgroundColor is set
- Only traffic charts should have filled area (fill: 'origin')
- Fixes visual bug where 20% memory usage appeared as 100% fill
