CH table metadata: omie.offers

OMIE auction OFFER CURVES (bid/ask blocks) — day-ahead (PDBF) + intraday sessions (PHF1..PHF7). OMIE publishes each curve twice: an anonymized daily file (`curva_pbc`, timely, `unit`='') and a per-unit monthly file (`curva_pbc_uof`, lagged, `unit` populated). Both carry the same blocks in the same order — the per-unit insert wins on merge (ReplacingMergeTree by inserted_at), so recent days may show `unit`='' until the monthly file lands. One row per curve block.
