fix: resolve CI lint errors and httpx dependency conflict

- Fix httpx version conflict: requirements-dev.txt now uses >=0.27.0 to match requirements.txt
- Extract CSAT helper functions to csatUtils.ts to fix react-refresh/only-export-components
- Remove default export from admin/EmptyState.tsx shim (same rule)
- Fix empty catch block in Modal.tsx (no-empty)
- Add eslint-disable comments for intentional setState-in-effect patterns in
  FlowAnalyticsPanel, QuickLaunch, NodeEditorPanel, useCachedQuota,
  MyAnalyticsPage, TeamAnalyticsPage
- Add eslint-disable comments for intentional _children destructure in NodeEditorPanel
- Fix _parentId unused var in useTreeLayout.ts
- Rewrite usePaginationParams.ts to avoid reading refs during render
