Add a scan progress bar with calculated time-to-completion based on motor speeds and count time etc. #384
Description
Part of #373 Queue Management & Experiment Control
Implement visual progress feedback including dynamic progress bars and remaining duration calculations during scan execution
Goals
Acceptance criteria : What journeys should the user be able to complete to consider your feature done
Be as specific as you can, check them off once they work. Add more if you find more requirements during development. Issue should only be considered done after all of them are checked
- The user can view an active scan's execution progress bar with an estimated time remaining.
Tasks
base on the goals, deduce the tasks required. check them off once they're done
- Duration Estimator: Build a calculator using motor speed, acceleration, range, and scan resolution to compute estimated plan runtimes, this most likely will be done with Bluesky simulation or something build into plan direction, to allow estimate of the plan progression.
- Progress Updates API: Subscribe to BlueSky plan event milestones to update progress bar states dynamically.

This overlaps with the proposed solution for Waffle:

Below include notes from a meeting with @EmsArnold.
Two existing estimators to evaluate before writing our own:
experiments, in which case an equivalent could be written for another beamline.
Worth establishing which of these we can consume, and whether either is accurate enough to
drive both the per-scan ETA and the whole-queue ETA required by #373, before committing to
motor-speed/count-time calculation in the UI. Though It is likely we will have to write our own for the beamline.
