Describe the bug

YourStats should show a bar chart for seven weekdays, but it's only showing two days in Safari. All seven days are present in the DOM inspector, but all are labelled with 'Invalid Date', except Monday.

To Reproduce

Steps to reproduce the behavior:

1. Go to https://zooniverse.github.io/front-end-monorepo/@zooniverse/fe-project/index.html?path=/story/project-app-screens-classify-your-stats--your-stats#storybook-preview-wrapper in Safari.
2. Navigate the bar chart with VoiceOver and you'll hear 'Invalid Date: 0' for all the missing days.

Expected behavior

The chart should have seven days, each labelled with name of the day in your locale.

Additional context

I think this might have broken when stats moved over to the new stats API. Maybe the mocks for this story weren't updated?

[eatyourgreens]

In Firefox, there are only 6 days, and they are shown in reverse order (Saturday on the left, Monday on the right.)

The chart looks fine on live projects, so I think the problem might be the mock data used by the stories and tests.
