With the vector-sync gauge flake fixed, the plotly test now reaches the UI
phase. On a loaded nc32 CI runner the Astrolabe SPA can take >10s to mount its
search component, so `.mcp-search-input input` wasn't visible within the old
10s budget (playwright TimeoutError). Bump to 30s, matching the loading-
indicator wait just below. nc31 already rendered well within budget.
