fix(chart): fail loudly instead of generating random secrets on lookup miss

randAlphaNum fallbacks silently minted new db/redis/rustfs passwords on
every cluster-less render (always the case under Argo CD's helm
template), overwriting live credentials. Fresh installs now get a clear
error demanding explicit values; helm upgrades are unaffected (lookup
preserves existing secrets).
