fix(eso): chart 0.6.1 - fullnameOverride to keep SA names stable

The ESO subchart was prefixing the ServiceAccount with the parent
release name (qsoft-platform-external-secrets), breaking both
ClusterSecretStore.serviceAccountRef and OpenBao's role binding which
both expect plain 'external-secrets'. Lock the name via
fullnameOverride.
