Continue tidying the flat ui/ root: - ui/statusbar/: statusbar.rs becomes statusbar/mod.rs (its crate::ui::statusbar::* paths are preserved) and absorbs statusbar_config.rs + statusbar_menu.rs. - ui/window/: the standalone manager/dialog windows move here — about, layout_manager, page_setup, plugin_manager, shortcuts, layers, update_notice, open_progress. The crate::ui::LayerPanel re-export is repointed so callers are unchanged. Call sites repointed to the new paths; no compat re-exports beyond the existing LayerPanel one. ui/ root drops from 21 to 10 flat files with five subdirs (ribbon, style, popup, statusbar, window).
