hub(ui): tabs display for system + major frontend/charts refactoring

- System page tabs display option
- Remove very specific chart components (disk usage, container cpu, etc)
and refactor to use more flexible area and line chart components
- Optimizations around chart handling to decrease mem usage. Charts are
only redrawn now if in view.
- Resolve most of the react dev warnings
