fix(tables): remove inline font override in auto-resize, guard undefined columnOrder

- Remove `font:inherit` from measurement span inline style so Tailwind
  classes (font-medium, text-small) control font properties for accurate
  column width measurement
- Only include columnOrder in metadata update when defined, preventing
  handleColumnRename from clearing a persisted column order when
  columnOrderRef is null
