More sustainable way to store timer values (for charging screen timers)

[bracyw]

Description

Currently total times are stored in as values in sessionStorage, to allow for the total time to be saved if the page reloads. However, these timers are not true to the entire charging session. We need a way to have the timers that track charging status's that is actually true. That is either first messages received by the client or preferably values tracked using the server.

Acceptance Criteria

Timers for charging status's (connected to the combined-status-display component) are true to values read from the car.

Proposed Solution

Talk to Reid or Wyatt (Wyatt might need to talk to Wyatt).
