Search specific financial metrics

Pull named financial line items across one or more companies in a single call. Body takes tickers and line_items (both required, both arrays), plus period (annual, quarterly or ttm) and limit. Returns search_results with one row per ticker and period carrying only the fields you asked for, alongside report_period, period and currency. Use it to build a comparison table without pulling three full statements per company. The item names are the same field names the statement tools return, so look one up there first if unsure. For everything about a single company use get_financial_financials.
