Clear stale ChatGPT OAuth fallback links

Manual authorization links now behave as transient recovery state: a fresh login clears older URLs, a successful copy clears the exposed URL before polling, and logged-in status defensively drops any stale manual link.

Constraint: OAuth authorization URLs should not survive beyond the active recovery action.

Rejected: Keep the copy button after a successful copy | that leaves an expired authorization URL visible after later auth state changes.

Confidence: high

Scope-risk: narrow
