fix: return empty badge for frontend_only nodes (GREEN)

Special-case 'custom_nodes.frontend_only' in getNodeSource() to return
empty badgeText instead of 'frontend_only'. This prevents frontend-only
nodes (e.g. rgthree Reroute) from showing a misleading 'frontend_only'
badge that obscures user-set titles.

Fixes #9997
