feat(app): voice on the Navara engine

createViewerlessTools creates the voice commands with viewer: null on the
engine (tools.js passes it the voice options and place search), so
window.__gevVoiceCommands exists in ?engine=navara: the W1 tools drive the
engine and the viewer-only tools answer UNAVAILABLE_ON_ENGINE. The Cesium
path hands its engine to initGevVoiceCommands explicitly.

viewerlessTools.test.mjs: the Navara tools now return voice commands
(created without DOM through injected control and session stand-ins),
whose runner answers get_current_view_state on the engine and refuses
control_scene; the debug handle carries them and teardown removes them.
