feat(ui): polish domains UX and dark-mode loading accents

Group service domain tables with inline redirect controls, live-save
redirects without full refreshes, and only auto-pair www hosts when a
www redirect is active. Align helper tooltips, server-timing HUD, and
loading spinners with dark-theme accents; default theme-color to dark.
