This change makes plot generation asynchronous so the UI stays responsive during potentially expensive calls into openmc.lib. It introduces a background worker thread for id_map/property_map, queues plot updates, and updates the view when results are ready. A status‑bar busy indicator translucent overlay on the plot provides feedback while plots are generating. Let me know what you think!

This is really nice. Being able to interact with the app window while plots are being generated is a huge plus.

I like the status indicator and status bar text idea, though the status bar indicator was a little subtle to me, particularly on a wider monitor. I tried combining the two into an overlay in the plot image area. What do you think?

@pshriwise Interesting, can you throw that on another branch for me to play around with? If I like it, I'll merge it into the branch here
