feat(tools): migrates object_topology to functional TypeScript component

[hodanoori]

Summary

Migrates object_topology.jsx from a React class component to a functional TypeScript component as part of the React 19 migration epic (#1774).

Changes Made

• Replace class component App with functional component ObjectTopology in TypeScript
• Convert class state (filterCollapsed, selectedTypes, details) to useState hooks
• Replace componentDidMount / componentWillUnmount with a single useEffect with cleanup
• Replace UNSAFE_componentWillReceiveProps with useEffect watching the objects prop
• Remove Graph.nodeLabel call — not needed in the functional implementation
• Add TypeScript interfaces for TopologyObject, Details, and ObjectTopologyProps
• Fix onBlur on the filter dropdown to properly collapse it instead of console.log
• Add object_topology.test.tsx with 21 unit tests covering mount/unmount, filter dropdown, graph node/link filtering, and details popover
