fix: pass selection mode generic to ComboBox validate type (adobe#9795)

lixiaoyan · claude · web-flow · commit cc6d6a92713c · 2026-03-16T23:40:45.000Z
ComboBoxProps was using `Validation&lt;ComboBoxValidationValue&gt;` without
passing the `M` generic, so the validate callback's `value` field was
always typed as `Key` (single mode) even with `selectionMode="multiple"`.
