The badge-deduplication helper was extracted from InfoStandWidgetUserView in the prior commit; it's a pure (badges[]) => badges[] function that keeps slot indices stable by replacing duplicate codes with empty strings. Coverage: - empty input - unique-only passthrough - duplicate-replaced-with-empty - falsy entries (null / undefined / '') normalized to '' - first-occurrence-wins semantics - order sensitivity (same multiset, different order -> different output)
