[feat] Add Partner Nodes virtual category and rename license filter (#6542)

This PR adds a 'Partner Nodes' virtual category that filters templates
where OpenSource === false, and renames the 'License' filter to 'Runs
on' with values 'ComfyUI' and 'Partner API'. The implementation is
backward compatible and works like the existing 'Basics' category - it
filters templates from any category without duplication. The filter
logic now uses the explicit OpenSource field instead of heuristic
detection. This change coordinates with upcoming workflow_templates repo
updates that will move API templates to GENERATION TYPE categories and
add the OpenSource field to all API node templates.
