refactor(navbar): extrair NavbarShell e adicionar variante navbar no Button

Unifica a estrutura da navbar entre o app e a landing page via novo
componente NavbarShell. Centraliza estilos de botões da navbar na
variante `navbar` do Button, eliminando nav-styles.ts e as classes
inline duplicadas. AnimatedThemeToggler, RefreshPageButton e MobileNav
passam a aceitar prop `variant` para adaptar ao contexto.
