V48 Gate 3 (implementation-only): stalled wallet-auth redirect exposes its authorize URL + manual continuation

Diagnosis so far (staging Supabase auth logs): the browser click never
issues the /auth/v1/authorize request — GoTrue itself is correctly
configured (a direct probe 302s to the bitcode.exchange
/tps/wallet/authorize page). The stall is client-side between building
the authorize URL and the navigation leaving the page.

The panel now logs the exact authorize URL ([Bitcode QA]
'oauth-redirect' / 'oauth-redirect-stalled' events) and, when the
redirect watchdog fires, renders an 'Open Bitcoin authentication
manually' link carrying that URL inside the error alert — a
user-gesture navigation that both works around and pinpoints whatever
is cancelling the programmatic assign.
