Improve admin panel UX with toasts, evolution CRUD, sorting, drag-and-drop, and responsive layout

Add sonner toast notifications to all mutations, evolution management backend
(CRUD endpoints with search/pagination) and frontend (form modal with pokemon
selector, paginated list page), sortable AdminTable columns (Region/Gen/Year
on Games), drag-and-drop route reordering via @dnd-kit, skeleton loading states,
card-styled table wrappers, and responsive mobile nav in AdminLayout.
