Last Bluesky plot

[GRyall]

As a electrometry user/Instrument scientist I would like to see the last blue-sky plot at the bottom of the web dashboard page for the instrument. This would allow scientists to check on their phone how things are progressing without logging in. CK can speak more about this.

Views of how achievable this is, gratefully received. Also should I have put this on the Bluesky repo?

Have a discussion about high-level approach and come up with an architectural sketch of how this works before proposing this ticket.
