Run a what-if scenario on the tenant's ledger and forecast, and return the P&L and the cash forecast, baseline vs scenario

Run a what-if scenario on the tenant's ledger and forecast, and return the P&L and the cash forecast, baseline vs scenario. Give either levers ([{ type, params }], see kphi_scenario_levers) or the id of a saved scenario. Returns: the pro forma P&L over the horizon (revenue, COGS, gross margin, payroll, other opex, EBITDA, D&A, EBIT, interest, tax, net income) for the baseline and the scenario; the P&L per month (baseline and scenario); the cash impact per month and cumulated; and the cash forecast (baseline closing cash per month, and the scenario's = baseline + cumulated cash impact). Computes only; nothing is saved (use kphi_save_scenario, with the same levers and scope). The result is a PROJECTION — K-Φ's forecast summed over the horizon — not actuals: present summary_table verbatim, with its scope line, and lever_classes when a lever's account class matters. version is required when more than one exists.
