v0.4.9

Fixed

• Dashboard: VisionCallCard description scrollbar thumb never rendered:
  the ScrollArea wrapper hardcoded its Viewport to size-full
  (height: 100%), which does not resolve against a Root declaring only
  max-height (no definite height). The Viewport grew with content and
  never overflowed, so the scrollbar thumb was absent for long vision
  descriptions. Added an optional viewportClassName prop to the
  ScrollArea wrapper (merged via cn/twMerge after the default
  size-full); VisionCallCard now passes viewportClassName="max-h-40"
  so the Viewport itself is bounded to 160px and overflow triggers the
  thumb. Short descriptions still size to content (Root has no forced
  height). The 11 other ScrollArea callers are unchanged.
