Issue Fixes

• Fix field.eq(x) / field.in(..) on an array (list) field silently matching nothing when the filter runs as a collection scan
• Array membership is matched element-wise on the index path (arrays are indexed per element) but was matched by whole-value equality (deepEquals) on the collection-scan path, so a query's results depended on whether an index existed or was chosen by the planner. Combined with the 4.4.2 planner change (#1266) — which correctly relegates the non-winning-index filter to a collection scan — an AND of an indexed array eq and a bounded range on a second indexed field left the array eq running as a collection scan, where it matched no documents.
• EqualsFilter and InFilter now match an array/Iterable field by element containment on the collection-scan path, mirroring applyOnIndex, so results are the same regardless of index presence.
