trip-budget-report

Summarize what an Everway trip costs from the itemized costs on its itinerary. Use when a user asks 'what's this trip costing,' 'total so far,' 'how much have I spent on hotels,' 'cost breakdown,' 'budget for the trip,' or wants spend grouped by category, day, or traveler. Reads itinerary items, groups costs by category and currency, and flags unpriced bookings so the total is honest.
