I've modified the PersistentSidebarProvider to automatically expand the sidebar when on the /dashboard/clientes route. The sidebar will remain expanded by default on this route, but users can still manually collapse it if needed. The system detects when navigating to the clients route and forces the sidebar to expand, while maintaining the normal cookie-based persistence behavior on other routes.

I can see from the image that you want a hierarchical menu structure with "Cadastros" as an expandable submenu containing Inversor, Módulo, Base de Dados Solarimétrico, Integrações, WhatsApp, and Parâmetros. Let me read the current sidebar structure and implement this menu organization.

I've implemented the hierarchical sidebar menu structure as shown in your image. The menu now includes the M1-M6 numbering system with "Cadastros" as an expandable submenu containing Inversor, Módulo, Base de Dados Solarimétrico, Integrações, WhatsApp, and Parâmetros. The submenu automatically expands when you're on any of its child routes and can be manually toggled with a chevron icon.
