 Buyer-raised complaint tied to a [[PurchaseRequest]]. Captures the reason, priority, category, an array of evidence uploads, a chronological `timeline` of actions, an optional resolution, and SLA deadlines. An admin (`adminId`) is assigned during triage and resolves the dispute with a structured action (`refund`, `replacement`, `compensation`, `warning_seller`, `ban_seller`, or `no_action`).
