chore!: Drop the direct product-config dependency

Remove the Configuration impl for MetaStoreConfigFragment and the product-config
crate from the workspace. product-config now only appears transitively via
stackable-operator. The deploy/config-spec packaging is left in place to mirror
trino-operator (it is operator-templating-managed infrastructure).
