State pages: Show only the relevant fee rates

[coreycaitlin]

In the contextual information about the fee rates at each stage of the production process, we should only show the rates for commodities actually produced in the current state. For instance, if Massachusetts doesn't have coal production, we don't need to show the fee rates for coal production on that page.

This is underway in #1450. Closing this issue in favor of that one.
