Include Insight Categories in GAL Export with GC/GI Mapping

NetBrain currently does not support exporting Insight Categories together with the Global Assumption List (GAL), and there is no mechanism to map Golden Configurations or Golden Intents to Insight Categories during that export, whether through YAML or the GUI. This enhancement proposes adding the ability to include Insight Category assignments in the GAL export process and to define GC/GI-to-Insight-Category mappings using either a YAML configuration or a graphical interface. Customers managing Network Intent definitions would benefit from a more complete and portable export that preserves Insight Category classifications, reducing manual remapping effort when moving or replicating configurations across environments.
