fix: resolve SSR prerender errors for login and profil pages

- Fix window.location usage in tirages page by adding SSR check
- Fix router.push call during SSR in profil page using useEffect
- Extract GoogleLoginButton to separate component to fix OAuth provider context
- Add null safety check for user object in profil page
- All pages now prerender successfully without errors

This fixes the 404 page not found error by ensuring proper SSR/CSR separation.
