OAuth redirect parsing can crash on malformed callback URLs

Steps to reproduce

Complete a login flow that returns an unexpected redirect URL, especially one with no query string or malformed parameters.

Expected behavior

The app should reject the callback cleanly and show a readable login error.

Actual behavior

The redirect query parser assumes every pair contains =, so malformed URLs can crash the login flow.

No? This is false, we catch all those malformed urls at the top level caller and show a toast when it happen. Please show me such a adversarial malformed url that will cause the app to crash.
