rename: prefix gateway projects/namespaces with ZB.MOM.WW + sln→slnx

Apply the ZB.MOM.WW. prefix to all gateway-side projects, folders, .csproj/.sln contents, C# namespaces, using directives, generated proto C# (csharp_namespace + checked-in generated files), InternalsVisibleTo attributes, project-name string literals (LoadProject, .sln lookups, worker exe paths, staticwebassets manifest), and the install/script/doc references that point at any of the above. Migrate the solution from .sln to .slnx via `dotnet sln migrate` and delete the old file. External-runtime identifiers are intentionally NOT prefixed so external configuration keeps working: - GatewayMetrics.cs MeterName ("MxGateway.Server") - DashboardAuthenticationDefaults Scheme/Policy ("MxGateway.Dashboard") - GatewayRequestLoggingMiddleware logger category ("MxGateway.Request") - StaRuntime thread name ("MxGateway.Worker.STA") - appsettings.json root section "MxGateway" + env-var prefix MxGateway__... and secret-name MxGateway:ApiKeyPepper - C:\ProgramData\MxGateway\ data dir paths Also fixes two tests that were not rename-related but became visible while validating the rename: - WorkerLiveMxAccessSmokeTests.ShutDownAsync: cancellation that the gateway service correctly maps to RpcException(Cancelled) per gRPC convention was being misclassified as a stream fault. Added a sibling catch on RpcException with StatusCode.Cancelled. - IntegrationTestEnvironment.ResolveRepositoryRoot: extracted IsRepositoryRoot and made it accept either a .git marker OR a .sln/.slnx next to src/ so the worker-exe walker works in non-git working copies. clients/proto/proto-inputs.json's protoRoot updated to point at src/ZB.MOM.WW.MxGateway.Contracts/Protos. Verified by `dotnet build` and a full `dotnet test` of the .slnx with MXGATEWAY_RUN_LIVE_{MXACCESS,LDAP,GALAXY}_TESTS=1: Tests: 472/472 pass Worker.Tests: 280/280 pass (4 dev-rig [Fact(Skip=...)] skipped) IntegrationTests: 18/18 pass Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
