The default K8s auth policy already provides namespace-scoped access to
kv/data/kubernetes/namespace/{namespace}/{sa}/* via identity templating.
Forgebot secrets should be stored at kv/kubernetes/namespace/forgebot/default/*
instead of kv/service/forgebot/*, eliminating the need for 5 individual
policies. The forgebot K8s auth role is kept for the forgebot-operator SA.
