feat: add account menu and redirect after Q&A logout

Add the top-right account icon with the signed-in name and logout link. Expire the Q&A session before redirecting to the configured inquiry homepage in both environments. Preserve login return URL checks and ignore request-controlled logout destinations.

Validation: 106 tests, syntax checks, and mocked Chromium desktop/mobile regressions pass, including session-cookie removal and the destination navigation request with external networking blocked.
