Fix measurement control page timeouts

The measurement control page could time out on procedures with millions of measurements, leaving the Pareto charts unable to load.

• Fixed the measurement control page timing out on large procedures, so the Pareto and Cpk charts load reliably.
• Improved how historical measurement data is aggregated in the background, keeping the page fast as your data grows.
• Fixed the live runs toggle getting stuck on "Reconnecting" after a connection drop.
