feat(ticket): redesign native ticket admin page UI/UX

- Fix empty status/department selects in the detail panel (printf leak)
- Replace dead 代客提交 button with a working collapsible create form
- Error-aware notices; redirect keeps filters and the open ticket
- Status views with counts, incl. 未关闭 default and 已关闭 view
- Two-column detail: conversation + attachments + prereplies | info,
  status/department/assignee select, internal notes; closed = read-only
- Split detail panel into UsersMenusTicketsDetail trait; page-scoped
  tickets.css / admin-tickets.js replace inline styles
- AdminListPagination accepts parent file so users.php keeps menu highlight
- Drop native loading="lazy" per lazyload contract
