// Phase 14 end-to-end coverage for the rename-planet flow. Boots an
// authenticated session, mocks the lobby + report + order routes,
// drives a click into the renderer to select a planet, opens the
// Rename action, types a new name, submits, and verifies the
// optimistic overlay (inspector + map label). A second test covers
// the rejected path: the engine answers `cmdApplied: false` and the
// inspector keeps the original name while the order tab row reads
// `rejected`.
