Move to Websocket Protocol (or Similar)

DOES:
Current dashboard (1.3.0) uses static HTML to display in browser. Must refresh the browser to view updated information.

SHOULD:
Dashboard should update dynamically (full-duplex) in real-time (or near real-time).

Using websocket (ws) protocol is too heavy for this use case (don't need duplex communication). Instead, looking at server sent events (SSE) technique that sits on HTTP. Simplex communications and lighter weight.

Some GitHub examples to consider: https://github.com/kljensen/golang-html5-sse-example and https://github.com/dustywilson/sse.

Or could also just add meta tag in HTML (e.g., <meta http-equiv="refresh" content="5">)
