Description: Summary Fixes the two reported OAuth UX failures (no popup after Add MCP; 'Reopen authorization window' pressing doing nothing): Popup-first: window.open previously ran after awaiting /api/mcp/oauth/start, outside the browser's user-activation window, so the popup was silently blocked — worst on the add-server flow (two awaits deep). The hook now opens about:blank synchronously in the click (named per server, so a re-click focuses/reuses an existing authorization window), navigates it once the start returns, and closes it on failure/already_authorized. A genuinely blocked popup shows a clear toast and skips the request entirely. Bounded start: /oauth/start had no client-side timeout, so a stalled start (the known transient body-stall) held the re-entrancy guard and the connecting label indefinitely — the button looked dead. The request is now bounded at 30s; on timeout the popup closes, the label resets to 'Connect with OAuth', and retry is immediately available. The mutation no longer opens windows (returns authorizationUrl + state); popup lifecycle lives in one place. Residual note: the add-server auto-start still sits after the create request, so an extremely slow create+probe can still exceed the activation window — but it now degrades to a clear 'Popup blocked' toast and a clean, clickable 'Connect with OAuth' state instead of a stuck label. Type of Change Bug fix (UX) Testing Hook tests updated + 2 new: popup opens before the start request resolves (popup-first ordering), and a blocked popup skips the request and leaves the row idle. 10/10 green; tsc + biome clean.
