> When importing a flow (via upload, paste, or creating a versioned process group) that references a Parameter Provider with a bundle version not available in the system, NiFi fails to create the Parameter Provider even when only one compatible version is available.
> For processors and controller services, NiFi applies fallback logic via discoverCompatibleBundles() to resolve to an available bundle version. However, this method was not being called for Parameter Providers during flow import operations in ProcessGroupResource.java.
> Impact: Parameter Providers referenced in imported flows are not created when their exact bundle version doesn't match, even though the component type is available with a different version.
> Fix: Add serviceFacade.discoverCompatibleBundles(flowSnapshot.getParameterProviders()) calls alongside the existing discoverCompatibleBundles(flowSnapshot.getFlowContents()) calls in the proper code paths.
