chore(DEV-460): delete orphan apps/platform-prod

The three sealed secrets under apps/platform-prod/ and the
apps/app-platform-prod.yaml ArgoCD Application are the
pre-consolidation era from DEV-203. The values live in
apps/paperclip/paperclip-secrets-sealed.yaml today, and Paperclip
reads them from the paperclip namespace. Approved cleanup path
per DEV-459.

Pocket ID OIDC client stays registered; harmless if PR #3040
lands upstream.
