The search sort sheet had two identical releaseDate entries. Remove the duplicate without changing sorting logic: descending dates show recent releases first, ascending dates show older releases first, and unknown dates stay last.

The rendered sheet regression observed two release-date options (Red), then a single option and unique field identities (Green). Existing date-order tests pass in both directions. Lint/typecheck passed; 22 focused tests and 3,228 full Jest tests passed, with 11 skipped. The non-destructive Maestro flow exercises both directions but was not run because Maestro is unavailable. No device validation, merge or deployment is claimed; account and collection data were not changed. Follow-up to beta umbrella #868.
