Switch user admin handling from an AppUser boolean to ASP.NET Identity roles. Removed AppUser.IsAdmin and related configuration/model entries; added migration ReplaceIsAdminWithRoles to copy Users.IsAdmin=true into a persistent admin role and drop the IsAdmin column. CurrentUserResponse now exposes roles (string[]), AuthController returns ordered roles from UserManager, and IdentitySeedService now ensures the admin role exists and assigns/creates an initial admin user in that role. Program.cs registers an Admin-only policy (PolicyNames/RoleNames), adjusts cookie auth events to return 401/403 for API requests, and wires up authorization. Frontend updated to use roles: authSession normalizes roles, adds hasRole and ROLE_ADMIN, router and layout support meta.requiredRoles, and new Forbidden and AdminUsers pages/route are added. codexInfo.md updated to reflect the migration to role-based auth.
Introduce a global app banners store (GUI/src/stores/appBanners.ts) and switch authentication error/notification flows to use it. GUI/src/Layout.vue now consumes the banner store, replaces the single snackbar with a stacked, dismissible banner UI (styles, transitions and z-index included), and adds navigateToBrandTarget() to route the brand button based on auth state. GUI/src/routes/authentication/Login.vue was updated to push errors to the new banner store and remove the local alert. Minor route adjustments in GUI/src/plugins/routesLayout.ts: rename 'Dash' to 'Dashboard' and change Login visibility to Unauthenticated. codexInfo.md updated to document these UI/behavior changes.
Introduce a complete frontend auth flow and protected dashboard.
- Add auth session module (GUI/src/services/authSession.ts) with fetchCurrentUser, login, logout, caching and structured errors.
- Add Dashboard page (GUI/src/routes/dashboard/Dashboard.vue) and a protected Dashboard route (meta.requiresAuth) at '/'.
- Move public landing page to /welcome and mark it Visibility.Unauthenticated; update 404 and Impressum links.
- Implement router guard (GUI/src/router/index.ts) to redirect unauthenticated users to Login and prevent logged-in users from accessing guest-only pages.
- Update routes layout (GUI/src/plugins/routesLayout.ts) to include authenticated/unauthenticated visibility and dashboard entry.
- Update Layout.vue to track current user, show username/menu, conditionally render sidebar items, add logout flow and error snackbar, and insert visual divider before auth-only items.
- Convert Login.vue into a working login form with loading state, error handling and redirect after success.
- Update codexInfo.md to document the new auth features and related UI/route changes.
Refactor Layout.vue to implement a redesigned, responsive shell: new branding (SVG icon, title & subtitle), computed sidebar/footer routes, route-aware page title & description, improved footer visibility, and a mobile-friendly navigation drawer. Theme handling now uses a data-theme attribute, persistent storage, accessible labels and toggle controls. Added new image assets (icon.svg, icon.png, 404NotFound.png), global.css and documentation files (style.md, codexInfo.md), updated related plugins/routes/components, and removed the old logo.png. Also updated the favicon.
Add a Vuetify-powered application shell (Layout.vue) replacing the previous App.vue, including app bar, navigation drawer, theme toggle, footer and localStorage persistence for theme/drawer. Introduce a routesLayout plugin with a Visibility enum and centralized LayoutRoute definitions; add route components (Home, Impressum, Login, 404NotFound) and update the router to build routes from the new layout definitions. Register Vuetify in main.ts and add dependencies (vuetify, @fontsource/roboto, @mdi/font) in package.json; update tsconfig.app.json to include .ts files. Package-lock.json updated accordingly.
