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.
