perf(desktop): lazy-load renderer routes and pause polling when hidden

Drop the eager Antd global import in favour of unplugin-vue-components
on-demand resolution, async route components, defineAsyncComponent for
the shell/login split, and a dynamic Modal import inside
showClientActionError. Pair that with a visibility-aware runtime poller
that stops the 15s snapshot refresh when the window is hidden and kicks
off an immediate refresh on re-show. Refresh DesktopShell nav with
inline icons and a calmer active/hover treatment, and land
ActionButton/DisclosurePanel/PaginationBar primitives for upcoming
views.
