feat: add mini table header rendering for dynamic header height

- Mini table now includes a header row that mirrors real table headers
- Header height is measured from mini table when prop.headerHeight is not set
- resolvedHeaderHeight computed falls back to measured header height
- Both row and header heights measured via ResizeObserver on container
- Update DEV_MODE_TS timestamp
