Bug: Generated context helper service_runtime_from_env missing register_executor call

Description

When running entity saves via AuditedSaveExt::save(&ctx), the runtime requires a type-erased helper DynGraphSaver to be registered.

However, the template used to generate the context builder (e.g. service_runtime_from_pool in runtime.rs) only inserts the executor as a generic resource:

context.insert_resource(ServiceRuntimeExecutor::new(mutation_executor));

Because it does not call context.register_executor(executor) explicitly, the DynGraphSaver trait object is never bound. As a result, calling .save() on any audited entity fails at runtime with:
graph write error: no DynGraphSaver registered — did you call register_executor()?

Expected Behavior

The context initialization helper should register the executor correctly so that graph saves can be performed immediately without manual registration workarounds.

Suggested Solution

Update the Rust code generator template for runtime.rs to call register_executor on the context:

let executor = ServiceRuntimeExecutor::new(mutation_executor);
context.register_executor(executor.clone());
context.insert_resource(executor);
