add simulationRoutes to store, display at base / route

[jbolda]

Motivation

To improve transparency and flexibility, we include a page at the root that lists all of the routes, and the ability to signal which response to return.

Approach

Pipe OpenAPI routes into the simulation store. Return these items through a small form to adjust that state. Also, pipe that state into the OpenAPI handlers to improve the usability.
