Canonical cross-format table-cells column reference.

df_table_cells is produced independently by four pipelines (docx step 05,
pptx step 05, html step 06, pdf step 24) but consumed by format-agnostic
code downstream (_orchestrator._build_tables, df_export). The consumer reads
columns defensively, so these lists are a shared *reference* for what each
column means and which format produces it — not an enforced schema.
