refactor: update menu and routing for ticket management

- Replaced references to "Solicitar Acesso" with "Abrir Chamado" across the application for consistency in terminology.
- Updated routing logic to reflect the new ticket management flow, ensuring that the dashboard and sidebar components point to the correct paths.
- Removed the obsolete "Solicitar Acesso" page, streamlining the user experience and reducing unnecessary navigation options.
- Enhanced backend schema to support new ticket functionalities, including ticket creation and management.
