Charging Screen Improvements

Changes

Implemented all of the todo below, to summarize:
added time based status lights (which save total times using sessionStorage, to avoid reset on page refresh)

and re-arranged existing components, adding more space for graphs (as well as merging changes to the graph component form #180)

Test Cases

• Manual

Screenshots

To Do

Any remaining things that need to get done

• Re-arrange/Combine Status Components:
  • Visual layout resembling the inner state representation:
    • Active (current != 0)
      • Charging (control = 0)
        • Balancing or not
      • Paused Charging (control = 1)
        • Balancing or not
    • Inactive, faulted (state = 3) or not yet enabled (Charger/Box not sending messages)
• Update Pack Voltage and Cell Temp Graphs:
  • Ensure graphs show values across the whole charging session.
• Enhance Fault Component:
  • Make component bigger.
  • Include Sheperd faults.
  • Specify fault sources (BMS or Charging Cart).
• New Additions:
  • Label: Started charging at this timestamp.
  • Duration in Charging Mode and Balancing Mode for the whole session.
• Mobile page?
