forte-drop and forte-drop-mcp have hackathon-domain values hardcoded
(drop-k8s.hackathon.forteapps.net). Listing them in apps/base/
syncs them to both upc-dev and upc-prod overlays — prod sync would
create broken Applications pointing at non-existent prod ingress.
Move references to apps/overlays/upc-dev/ only.
