Domain Export/Import Support for API Stubs, Intents, Guidebooks, and Probes

NetBrain currently allows administrators to export and import device lists, credentials, sites, and AAM configurations between domains, but does not support export and import of API stubs, intents, guidebooks, or probes. This limits the ability to fully replicate a domain's configuration when standing up a new environment. This enhancement would extend the existing export/import functionality to include the database collections for API stubs, intents, guidebooks, and probes, alongside the currently supported items. Customers setting up new domains, such as for proof-of-concept or new customer onboarding, would benefit from a complete and consistent way to clone domain configurations without manually recreating these components.
