Compute dasher pay from deliveries

Given a list of delivery events for dashers (e.g., dasherId, pickupTime, dropoffTime, distance, tip, and optional bonuses) and a set of pay rules (e.g., base pay per order, per-distance rate, per-minute rate, and additive tips/bonuses), implement a program that outputs each dasher’s total pay for a shift or day. Requirements: (

1. Define and validate an input format and pay-rule schema; (
2. Handle overlapping deliveries, missing fields, and rounding to cents; (
3. Support grouping by day and by dasher, with output sorted by dasherId; (
4. Provide tests covering at least three different pay configurations.
