Add daily audit summary cross-checks to multiday report

Fetch reports_daily_audit_summary per day. Use cash_income total as the
reconciliation audit column (independent payment cross-check vs transaction
flow). Add a second Audit (DAS) column on the sales breakdown using
accrual_income totals alongside the earned revenue Audit (ER) column —
both highlight in amber if they diverge from the configured columns gross.
