Conform activity workbooks to bills and commit them for emissions calculation.
Conforms a client's arbitrary fuels-and-electricity activity workbook to the fuels-and-electricity-bills resource type and commits it so GHG emissions are actually calculated. Resolves each row's site against the site resource type FIRST (a bill's site is per bill, not per workbook), extracts bills from the source workbook, parks any row missing a required field, carrying an unrecognised fuel type, naming an unmatched site, or carrying a date that does not name a full day for triage rather than guessing, and commits the approved bills via qb.commit_ingest so downstream emissions processing can run.
