Denormalized per-program dispatch (PDBF, PDVP, BS, BT, RR, RTR, PHF1..7, PHFC, P48, BILATERAL, STARTUP_GAS_*, BS_ENERGY). One row per `(program, datetime, unit, ...discriminators)`. Enriched at write time with `agent_group` (BRP/SM canonical), `owner_group` (real owner canonical), `technology`, etc. from `esios.unit_physical_flat`. OFFER programs live in the sibling table `esios.archives_i90_offers` to avoid NULL pollution.
