Implement compute_pay(deliveries) to calculate a delivery driver's daily pay from a list of delivery records. Each record may include times, miles, base rate, and tip. Requirements: robust error handling for missing/invalid fields and sensible defaults or skipping; enforce minimum pay per delivery; and produce a per-day total. Follow-up: add a configurable 'peak hour' rule that increases pay for deliveries whose start times fall within specified time windows.
