fix: correct login callback and the logout redirect URLs in documentation

The documented callback URLs did not match the actual URLs used by Auth.js. The OAuth redirect URI should be /api/auth/callback/zitadel, not /auth/callback.
Additionally, the post-logout redirect URL in .env.example was missing the /api/auth/logout/callback path.
