Opportunities table reorders rows when a checkbox is toggled (QA 6.1) #768

Symptom (QA 6.1)

In the Opportunities table, selecting a commitment via its checkbox sometimes reorders the visible rows. The selected commitments stay selected, but the table re-sorts on selection, which is disorienting.

Why it's a bug

Selection should not affect ordering. Users are mid-flow trying to compare commitments; the table shifting under them breaks that flow.

Hypothesis

The selection state is being fed back into a sort comparator (e.g. selected rows bubble to the top, or the table re-renders with a different stable-sort tiebreaker that the comparator forgets). Find the sort path in frontend/src/recommendations.ts (or wherever the table is rendered) and confirm selection state is excluded from the sort key.

Acceptance criteria

• Toggling a checkbox does NOT change row order.
• The currently-applied sort column (Monthly Savings, etc.) remains the ordering basis.
• A regression test toggles two checkboxes across a multi-row fixture and asserts row order is identical before/after.
