refactor(nav): remover sidebar, unificar navegação na navbar

Componentes da sidebar lateral (app-sidebar, nav-main, nav-secondary,
nav-user, nav-link), sidebar.tsx e use-mobile.ts removidos.
Barrel exports órfãos de shared/hooks, shared/components/providers,
shared/lib/schemas e shared/lib/types também removidos.
Navbar recebe ajustes menores de markup e acessibilidade.
