fix(autoHeightBridge): simplify height measurement, ensure body/html sizing, and extend update timeouts

- remove getMaxHeight helper and measure using documentElement/body scroll/offset metrics
- ensure body/html have height: auto and minHeight/width set for accurate measurement
- force layout recalculation by reading html.offsetHeight before measuring
- add longer delayed update timeouts (3000ms, 5000ms) to improve stability
