The fire-and-forget call_service channel can command an entity but can't
ask it a server-side question that has no SupportsResponse service to ride.
Add one generic EntityQuery RPC for those, mirroring the call_service path
end to end (proto -> codec registry -> bridge sender + error translation ->
sandbox handler -> proxy helper):
- proto: EntityQuery {sandbox_entity_id, method, args, context_id} and
EntityQueryResult {result} (the return wrapped as {"value": ...} so
scalar/list/None are all representable). Gencode regenerated into both
_pb2 mirrors; drift guard passes.
- MSG_ENTITY_QUERY constant + REGISTRY entry added to both protocol/messages
mirrors.
- SandboxBridge.async_entity_query builds the request, remembers the context
before the id is reduced to a wire value, translates remote/closed errors
through the existing paths, and unwraps {"value": ...}.
- EntryRunner._handle_entity_query resolves the entity on the private hass,
invokes the named method with the decoded kwargs, and serialises the return
through the as_dict-aware JSON encoder; raised HA/voluptuous errors
propagate as channel error frames so main rebuilds the same shape.
- SandboxProxyEntity._entity_query is the proxy-side companion to
_call_service.
No proxy op is wired onto it yet — that is the next phase.
