Modern UI: Add Time to Chart Tooltips

[andrewbaldwin44]

Fixes #2467

Proposed Changes

• Add time to chart tooltips
  
• I am of the opinion that showing the user count on every chart label is redundant. With the charts connected, we can easily view the corresponding user count in the last chart
• Fix the colors of the chart to correspond with the old UI

I also added a few other minor fixes here (let me know if you prefer these to be in a separate ticket)

• setting the tables / charts on first load (another miss from changing the useEffect to useInterval in useSwarmUi
• Format the memory usage in the workers table (was never migrated to the new UI)
• LineCharts are now properly connected and will respond to screen resizing
