ui/phase-14: rename planet end-to-end + order read-back

Wires the first end-to-end command through the full pipeline:
inspector rename action → local order draft → user.games.order
submit → optimistic overlay on map / inspector → server hydration
on cache miss via the new user.games.order.get message type.

Backend: GET /api/v1/user/games/{id}/orders forwards to engine
GET /api/v1/order. Gateway parses the engine PUT response into the
extended UserGamesOrderResponse FBS envelope and adds
executeUserGamesOrderGet for the read-back path. Frontend ports
ValidateTypeName to TS, lands the inline rename editor + Submit
button, and exposes a renderedReport context so consumers see the
overlay-applied snapshot.
