Fix: filter dropdowns no longer cropped + close on mouse-leave

- Owners / Status / Columns dropdowns were being clipped by
  `overflow-hidden` on the task <section>, especially noticeable when
  the table held a single row (no body height to absorb the panel).
  Removed `overflow-hidden`; preserved the rounded-corner look by
  giving the toolbar `rounded-t-lg` and the table wrapper
  `rounded-b-lg` so the inner backgrounds still respect the section
  border-radius.
- The three filter dropdowns now close on `mouseleave` of their
  `data-*-root` element (the panel lives inside the root, so one
  handler covers both the trigger button and the panel).
  Outside-click and the existing trigger-toggle paths stay in place.
