Count rejected Liftosaur history records on Swift

[bhelm]

Summary

Fixes the skipped-record undercount documented in bhelm/noop#94.

Swift's for case loop silently omitted non-object history elements, so they never reached the skipped counter. The loop now visits every element, increments once when an element is not a dictionary, and leaves the existing malformed-object and valid-session paths unchanged. Android already has the intended behavior and remains the unchanged product control.

Tests

• Adds mirrored exact Swift/Kotlin coverage for a heterogeneous four-element history, including the valid session fields/order and exact skipped == 3 result.
• Fresh independent static review of the exact frozen union delta passed with no P0/P1 findings; this PR's frozen three-file patch is an exact reviewed constituent (patch SHA-256 e65b967dc296d09d5ea40776d7b21495b5b75c850917048e3f67091001187f1f).
• Combined Native validation on the reviewed union (c7571fd020d6947594eb79198ba88ece7ab4648824c312e0bbee9e14f1150d97) exercised this exact named test: Swift focused 1/1 passed; Swift affected 28 tests passed; Swift full 241 tests passed with 1 skip. Kotlin focused aggregate 7 tests passed; affected 35 passed; full 4,157 passed with 6 skips and no failures/errors.
• Evidence artifact: /root/whoop/validation/product-fixes-93-99-union-native/43-final-audit.txt (recorded 2026-08-20, exact union hash and named-test occurrence audit).
