Add capital project detail panel and connect it to route for single project

[TylerMatteo]

Closes #16

Summary

This PR builds out the panel for showing project details for a single project. It uses the existing /capital-projects/:managing-code/:capital-project-id route.

New dependencies

• Numbro - Used for formatting the future commitments total.
• date-fns - Used for date formatting and logic. If you've worked with Moment before, you can think of date-fns as serving a similar niche. I like it because it is function-oriented and based around the browser-native Date class.

Not included

There is one requirement in #16 not included here - the "fly to" functionality where the map moves to a bounding box of the selected project. I'm going to capture the issues I had implementing that in a separate Discussion or Issue and put forward some potential solutions and next steps.

This PR previously included an upgrade to maplibre-gl 4.5 from 4.4.1. 4.5 seems to have introduced a bug (or at least, an unintentional breaking change). I fixed it by pinning the dependency to ~4.4.1.

The animation when expanding and shrinking the panel is a nice touch
