Adds forte_drop as an external service entry in the upc-dev Homepage portal.
- Target host: https://drop.hackathon.forteapps.net (current Coolify deploy).
- One-line addition under `services > Apps` in `infra/values/upc-dev/homepage-values.yaml`.
- Will be retargeted to https://drop.forteapps.net once the K8s migration ships (spec in forte_drop repo: docs/superpowers/specs/2026-05-28-k8s-migration-design.md).
Zero risk — pure metadata, no cluster mutation beyond Homepage refresh.
