fix: render inventory actions menu in a portal so it is not clipped

The «عملیات» dropdown was absolutely positioned inside the table container,
which has overflow:hidden for its rounded corners, so the menu was clipped
below the table. Render it through a Portal with fixed positioning computed
from the trigger's rect (RTL-aligned to the trigger's right edge), tracking
scroll/resize while open.
