Outlier rejection analysis

- Compare how Theia'a method of filtering by simulated pairwise (from global) vs. actual pairwise measurements helps
- Add to HTML plot the front-end inputs after each outlier rejection step

Also, add interface to Dask backend to plot progress as front-end proceeds

Start by reviewing Theia’s simulated-versus-actual pairwise filtering and the existing HTML plotting and Dask backend interfaces. Define which front-end inputs must be shown after each outlier-rejection step and how backend progress should be exposed, then validate both the comparison and end-to-end progress visualization.
