fix(landing): strip isProduction from provider response and handle late-resolve redirect

- Destructure only githubAvailable/googleAvailable from getOAuthProviderStatus
  so isProduction is not leaked to unauthenticated callers.
- Add useEffect to redirect away from the modal if provider status resolves
  after the modal is already open and no social providers are configured.
