Replaces product-config's writer module. Lives in framework::writer and
renders hive-site.xml (Hadoop XML) and security.properties (Java properties),
matching product-config's output. Also scaffolds controller/build with
placeholders for the per-file builders.

… builders

Reshape ValidatedCluster (name, image, cluster_config, role_group_configs) and
validate via framework::role_utils::with_validated_config. Build hive-site.xml,
security.properties and core-site.xml via dedicated builders + the vendored
writer. Switch HiveConfigOverrides to v2 KeyValueConfigOverrides (key-by-key
Merge). product-config is now only referenced by the crd Configuration impl.

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).

Resolve the JDBC driver, Kerberos hive-site entries and the core-site decision
into ValidatedClusterConfig during validation, so hive_site/core_site builders
consume only ValidatedClusterConfig. config_map keeps an explicit `owner:
&HiveCluster` solely for the ObjectMeta owner reference. Rename the reconcile
binding `validated` -> `validated_cluster`.

Replace the vendored java-properties/Hadoop-XML writer
(rust/operator-binary/src/framework/writer.rs) with
stackable_operator::v2::config_file_writer, which hosts the same code
(moved there verbatim via operator-rs #1217 on the smooth-operator branch;
hive's copy was byte-identical to hdfs's, the canonical source). Drop the
now-unused java-properties and xml dependencies. The framework module now
only contains role_utils.

The base dependency tag moves from stackable-operator-0.111.0 to 0.111.1,
matching the other operators; cargo only substitutes a [patch] whose package
version matches, and the smooth-operator branch carries 0.111.1.

No behaviour change; rendered output is byte-identical by construction
(same code, new home).
