Add tests for invalid height payloads

Extend useAutoHeight tests to cover invalid payload cases: a prefixed but non-numeric payload ('__RN_SIZED_WV__:not-a-number') to exercise the isFinite branch, and a direct negative number (-10) to exercise the numericValue <= 0 branch. Both assertions verify that requestAnimationFrame is not called and the height remains unchanged, preventing regressions for malformed or out-of-range payloads.
