feat: dark/light theming system + design tokens (OMC design system port)

- Restructure design tokens into :root/.dark raw vars mapped via @theme inline
- Add light/dark/system theming: useTheme hook + FOUC guard + ThemeToggle
- Keep iamcavalli palette (primary #1A463C, accent #DEF168) and Geist fonts
- Derive brand-consistent dark palette (verde-nero bg, lightened primary)
- Add scrollbar utilities (.no-scrollbar/.thin-scrollbar)
- Install tailwindcss-animate, register via @plugin (Tailwind v4)
- Mount ThemeToggle in admin sidebar footer
