fix(ui): dark-theme audit — modal, edit panel, right-fade, nav/tabs, default buttons

Covers every remaining hardcoded light surface: .dialog .box (popup), tr.edit
panel (#fafafa), td.right-fade gradient (white sliver next to links), button.nav,
checkboxes, #stats, tabs, map tooltip, and thedevs-network#444 default-button text.
