Include column metadata in column-value item fetch

[omribz156]

Summary

• Add the missing column { id title } selection to fetch_items_by_column_value results.
• This matches the existing response model, where ColumnValue.column already supports column metadata.

Verification

• python -m venv .venv
• .\.venv\Scripts\python -m pip install -e .
• .\.venv\Scripts\python -m compileall src
• generated get_item_query(...) locally and confirmed the query includes column { id title }
• git diff --check

This was implemented with Codex assistance, with the patch kept focused and manually reviewed.
