Each match group card now has:
- Radio button to pick which row to keep as the base survivor
- "Customize columns" toggle showing only columns that differ
- Per-column selectbox to pick values from any row in the group
- Decisions stored as {action, survivor_idx, overrides} dicts
Added apply_review_decisions() that builds the final DataFrame by
applying survivor selection + column overrides without re-running
the dedup engine. Batch actions also use the new dict format.

Replace st.rerun() with on_click callbacks so decisions write to
session state before the natural rerun. Decided groups auto-collapse
with status in the label; undecided groups stay expanded. Added undo
button on decided groups.
