chore(historian): HistorianGateway Client/Contracts 1.1.0, typed error reason (#900)

Bump ZB.MOM.WW.HistorianGateway.Client + Contracts 1.0.0 -> 1.1.0 (historiangw#135,
release 6365f34). GatewayErrorReasons now reads Client 1.1.0's typed
HistorianGatewayException.StatusCode / ErrorReason / ErrorDomain (constants from
HistorianGatewayErrorReasons) instead of parsing grpc-status-details-bin itself; the
direct Grpc.StatusProto pin and reference are dropped (the client brings it). The
published client maps every RpcException to a HistorianGatewayException, so the
trailer fallback is not needed. Behaviour unchanged: FailedPrecondition +
AGGREGATE_NOT_SUPPORTED_FOR_TAG (domain historian_gateway.v1) ->
BadAggregateNotSupported, everything else keeps its handling.

Adds GatewayErrorReasonsTests (typed-property-only exceptions, so they fail against
the old trailer implementation); wire tests and docs/Historian.md updated.
