Platform: new ReleaseOrchestratorScriptService translates the Platform-level
script API surface into calls against the ReleaseOrchestrator scripts module
so clients that still target /api/scripts on Platform continue to work during
the transition. Program.cs wires the shim. ScriptApiModels gets a minor
contract alignment.
ReleaseOrchestrator: ScriptsEndpoints + ScriptRegistry + ScriptModels updated
to expose and persist script variables correctly. New integration test
(ScriptRegistryVariablePersistenceTests) covers the persistence round-trip;
new unit test (ReleaseOrchestratorScriptServiceTests) covers the Platform
shim behavior.
