ci: add workflow_dispatch trigger to CI workflow

fix: resolve all 25 ESLint react-hooks and react-refresh violations
Replace useEffect-based state resets in dialogs with React's render-time state adjustment pattern. Wrap ref assignments in hooks with useEffect. Suppress known third-party library warnings (shadcn CVA exports, TanStack Table). Remove warn downgrades from eslint config.
