Add ETag caching and Cache-Control headers for static assets

Wrap the static file server with middleware that sets a Cache-Control
header (public, max-age=1800) and generates per-process ETag values
based on a SHA-256 hash of the startup timestamp and request path.
When the client sends a matching If-None-Match header, the server
responds with 304 Not Modified and an empty body.
