Copilot 58c85dd1ce fix: guard structured JSON alignment paths against legacy JSONB columns (#8323) ...

* Initial plan

* fix: guard structured json alignment to fix Clippy CI failure

- Add `is_structured_json_field` function that only returns true for
  fields with both JSON extension type AND Struct Arrow data type
- Replace all usages of `is_json_extension_type` / `has_json_extension_field`
  with `is_structured_json_field` to prevent legacy JSONB binary columns
  from entering structured JSON alignment paths
- Fix logic in `FlatProjectionMapper::new_with_read_columns` to guard
  JSON type hint concretization for JSON2 columns only
- Fix `create_column` in show_create_table.rs to only emit JSON structure
  settings for JSON2 columns
- Move `mod tests` to end of flat_projection.rs to fix clippy::items_after_test_module
- Add tests for legacy JSON behavior

* fix: guard narrow_read_columns_by_json_type_hint with is_structured_json_field check
