Replace the two stacked sire/dam clade grids in StepClade hybrid mode with one unified grid where each card carries Sire and Dam toggle buttons side-by-side in its header (right edge of the title row). A single clade can become either parent; picking Sire on a card currently set as Dam atomically clears the Dam pick (and vice versa). Card body click is disabled in hybrid mode — only the toggles change selection. Mechanics: BuildLineageCladePatch extracts the per-lineage clear logic from the old OnLineageCladePicked into a patch builder so OnHybridParentPressed can compose multi-lineage patches into one atomic Patch call (the cross-clear case applies both lineage updates in a single Changed signal). UpdateHybridCards walks the unified card dictionary and syncs both toggle states + the card's selected highlight. Drops the old _sireCards / _damCards dictionaries and the OnLineageCladePicked callback, since hybrid mode no longer routes through the per-grid click handlers.
