The Bulma components/pagination partial is only used by BasePagination
and its two wrappers (Pagination.vue, PaginationEmit.vue); no other
component renders raw .pagination-* markup. Ports the rules we actually
use (base layout, item sizing, hover/focus/disabled states, is-current
styling, mobile/tablet breakpoints) into BasePagination's scoped styles,
using :deep() to reach slotted children. The theme override for
.pagination-link on .has-background containers moves into an unscoped
style block on the same component. Drops the now-unused @import.
