feat(discount): add DiscountRule entity and session discount-rule audit columns
New Discount domain: DiscountRule (generic per-tenant rule with 6 types, priority, combinable, validity window, and per-type target fields) plus its repository. PatientSession gains applied_discount_rule_id/label audit columns and setDiscount() now records the source rule. Migration creates the table and columns.
