Luke Mino-Altherr b23302f372 refactor(assets): consolidate duplicated query utilities and remove unused code
- Extract shared helpers to database/queries/common.py:
  - MAX_BIND_PARAMS, calculate_rows_per_statement, iter_chunks, iter_row_chunks
  - build_visible_owner_clause

- Remove duplicate _compute_filename_for_asset, consolidate in path_utils.py

- Remove unused get_asset_info_with_tags (duplicated get_asset_detail)

- Remove redundant __all__ from cache_state.py

- Make internal helpers private (_check_is_scalar)
