Update Navbar.vue and FormCleanings.vue for Improved Logic and UI Consistency

- Modified Navbar.vue to enhance form validation logic by allowing access when `import.meta.server` is true, improving handling of form states in specific routes.
- Updated FormCleanings.vue to replace the icon name from "bi:stars" to "i-heroicons-sparkles-16-solid", ensuring consistency with the icon library used across the application.

These changes aim to improve the user experience and maintainability of the components by refining logic and standardizing UI elements.
