fix(loyalty): use shared pagination macro on card detail transactions

Replace custom pagination with the shared pagination_simple macro
to match the cards list page pattern. Always shows "Showing X-Y of Z"
with Previous/Next — no longer hidden when only 1 page. Uses standard
Alpine.js pagination interface (pagination.page, totalPages, startIndex,
endIndex, pageNumbers, previousPage, nextPage, goToPage).
