plebeius e0ed510fc6 perf(react-doctor): fix compiler-blocking patterns, raise score 72→81
Replace sync setState-in-effect with keyed remount and render-derived patterns in app, error-display, topbar-edit-modal, catalog-filters; use useCurrentTime() instead of Date.now() in hot paths; fix conditional hooks, passive scroll listeners, lodash path imports.
