Popover animations now origin-aware

Popovers in the design system now animate in a way that feels intuitive. Previously, when a popover appeared above a trigger, it would animate upward—toward the trigger element—which users perceived as the animation coming from the wrong direction. Now the animation originates from the popover's attachment point and flows outward toward its final position, with a subtle scale effect that makes the motion feel grounded and intentional.

The component also ships with saner defaults: the align property now defaults to 'start', keeping popovers flush against their trigger element rather than centered. The sideOffset was reduced from 5 to 4 pixels for a tighter appearance. Animation timing now uses design tokens instead of hardcoded values, ensuring consistency with other components in the system.

These changes live in the @n8n/design-system package and affect any UI element that relies on popovers—dropdowns, tooltips, and contextual menus throughout the application.
