Part of establishing React patterns in Ghost is to build a well-defined
and fairly self-encapsulated app through which we can test assumptions
and define best practices. Our guinea pig is Post analytics for this
purpose. This PR creates a new React app (posts) using Shade (the new
design system).

Shade is our new design system that follows React best practices and
leverages third-party libraries extensively. It's built on ShadCN/UI
which is one of the most popular React UI libraries today. This commit
adds an (almost) empty React app, set up to be the a starting point of
Shade.
