Test Coverage and Reliability Improvements

Overview

This PR introduces a comprehensive testing strategy across the Seamless Auth codebase. The goal was to significantly increase confidence in system behavior, particularly around authentication flows, security boundaries, and infrastructure wiring.

The result is a robust suite of unit, integration, and end-to-end tests that validate both expected behavior and failure modes.
