Ubiquiti API Source Type Support for Device Discovery

NetBrain currently does not support Ubiquiti as an API source type within the API Server Manager, which prevents discovery of Ubiquiti devices through the platform's API-based discovery methods. This enhancement would add Ubiquiti as a selectable API source type so that Ubiquiti devices can be configured and discovered alongside other supported device types. Customers running Ubiquiti infrastructure would gain full device visibility within NetBrain without relying on manual workarounds.
