Implement auth guard and app branding improvements

Auth & Routing:
- Initialize auth before router guards to prevent race conditions
- Default all routes to require auth unless explicitly set to false
- Add initial route check to redirect unauthenticated users to /login
- Remove duplicate auth initialization from base module

App Branding:
- Add VITE_APP_NAME environment variable for configurable branding
- Replace hardcoded "Ariège" references with environment variable
- Update index.html, market composable to use dynamic app name

Mobile UX:
- Fix mobile dropdown auto-close on navigation item selection
