FE-1719: Polish Experiment and Optimization results

[kube]

Important

Experimental
Sweep controls require Parameter sweeps. Optimization progress and Sensitivity analysis also require In-browser optimization. The header and Details improvements apply to all experiments.

Summary

Experiment results now keep the name, status, and relevant progress in the header. Configuration and compute information are available in Details, including an explanation that a sweep's run count is a sampling limit for the selected parameter values or ranges.

Changes

• Plain experiments show completed runs; optimized sweeps show completed optimization steps, with failed runs visible when any occur
• Details includes the scenario, sampling limit, simulation timing, compute backend, active batches, and search summary, and closes when switching experiments
• Parameter controls distinguish testing an optimization step from sampling a selection and wrap in narrow panels
• Surface and sensitivity summaries use shorter labels, with method information available through help
• Sensitivity analysis orders parameters by descending Share, keeps ties stable, and places missing estimates last while preserving correlations and confidence indicators
• The experiment guide describes the updated controls, and a patch changeset covers the published package

Test coverage

• Results-model and panel tests cover progress labels, failure counts, Details contents, experiment switching, optimization controls, and chart layout
• Importance-view and visited-field tests cover descending shares, ties, missing estimates, confidence indicators, and chart summaries
• Existing panel and navigation tests cover fullscreen transitions and retained panel state

Builds, unit tests, TypeScript checks, and lint passed for Petrinaut and the website: 20 tasks in total. Repository formatting and architecture checks also passed.

How to test

All experiments

• Open Simulate > Experiments and run an experiment
• Open its results and check that the header shows the name, status, and completed-run progress
• Open Details and inspect the scenario, requested runs, timing, and compute backend
• Switch to another experiment and confirm Details closes

Sweeps and optimization

• Enable Parameter sweeps and In-browser optimization in settings
• Create an optimization with multiple swept parameters
• Check that the header counts optimization steps and the parameter controls show the current step's sampled runs
• After optimization completes, move a parameter control and confirm the status shows sampling progress for the new selection
• Open Details and confirm the sampling limit is explained separately from optimization progress
• After importance estimates arrive, confirm the Sensitivity analysis rows descend by Share
• Expand the results to fullscreen, then return to the panel and check that chart choices remain selected

Consolidated into #9725, which now contains the experiment creation, results, and optimizer-control changes. The active stack is #9752, with #9728 based directly on #9725.
