fix(infra): drop bad postgres securityContext + un-own shared namespace
Address Codex review on PR #17:

[P1] Postgres official image's entrypoint requires root to chown a
fresh PVC, then drops to the postgres user via gosu. Forcing
runAsNonRoot+runAsUser=999 blocks the chown and initdb fails on a
fresh volume. Drop the securityContext; matches the existing
vaultwarden-postgresql pattern.

[P2] The forte-drop namespace was declared as a managed resource
in the postgres Application. Since minio lives in the same
namespace from a separate Application, an Argo prune of the pg
app would delete the namespace and cascade-delete minio. Remove
the Namespace resource; rely on syncOptions: CreateNamespace=true
on both apps (already set).
