CRDCDH-2450 Add react-specific caching policies

[amattu2]

Overview

This PR changes the production Nginx caching policies to align with a more React-specific deployment. Specifically:

• Enforce NO caching on the index.html file, which references the React chunks
• Enforce 1hr max cache on the injectEnv.js file
• Enforce a 1mo cache duration for most static assets

These are somewhat arbitrary baselines, but we can adjust as needed.
