Eric Hare 9690e69e86 fix(security): remove the disabled Python Code Structured tool component (#13560)
* fix(security): remove the disabled Python Code Structured tool component

Follow-up to #13538, which neutered PythonCodeStructuredTool to a
non-executable stub "for one release cycle, full removal later." This
completes that removal.

- Delete the component and its registration in lfx.components.tools.
- Drop its entry from the component index (num_components 355 -> 354,
  sha256 recomputed surgically) and from stable_hash_history.json.
- Remove its 18 i18n keys from every locale file.
- Replace the dedicated stub unit test with a removal test in
  test_dynamic_import_integration.py.
- Add a regressions entry to regressions/1.10.x.yaml.

The unauthenticated public-build RCE fix (report H1-3754930) is
unaffected: PythonCodeStructuredTool stays in
CODE_EXECUTION_COMPONENT_TYPES, so build_public_tmp still rejects any
saved or crafted flow that carries the type. instantiate_class execs the
node's stored `code` field regardless of whether the class still exists,
so the type-name block -- not the class -- is what closes the path.
