Add pgroup handling in dewars and enhance ShipmentDetails UI

Introduced a new `pgroups` attribute for dewars in the backend with schema and model updates. Modified the frontend to display `pgroups` as chips, integrate new visual icons for pucks and crystals, and enhance the UI/UX in `ShipmentDetails` and `DewarStepper` components. Added reusable SVG components for better modularity and design consistency.
