Update Charts from 3.6.0 to 4.0.3 via CocoaPods

Next, we'll move it to Swift Package Manager, to make progress on
running the app on Xcode 14.0.

The upgrade also required to:

- Rename `IAxisValueFormatter` to `AxisValueFormatter`
- Update a `Description` access now that it's no longer `Optional`
- Update a `.fill` assignment to match new types modeling

See ChartsOrg/Charts@v3.6.0...v4.0.3
