[Reporting - UI] Update chart to display real data for messages sent/received by date

[reichert621]

Problem
At the moment, the reporting page is just showing fake data. Let's update it to show real data.

• The reporting page can be accessed at http://localhost:3000/reporting

The reporting page (with fake data:)

Solution

• Pass real data into the chart component responsible for rendering this info (currently <MessagesSentVsReceivedChart />)
• Make any tweaks necessary to the chart UI

Context
See #252
