- Require reports_sales grant on postUnsuspend; return 403 on denial
- Reject unsuspend of non-SUSPENDED sales; skip silently on invalid state
- Move clear_all() after validation so an invalid sale_id no longer wipes
the active in-progress cart
- Null-guard get_sale_status() on missing row instead of fatal property
access; widen return type to ?int
- Fix getSaleType null-coalescing — CI4 session default only fires when
key is unset, not when value is null
- Rename get_sale_type → getSaleType, sale_id → saleId (PSR-12 camelCase)
- Extract SaleFixtureTrait with createSale()/createSuspendedSale(); add
regression coverage for auth denial, status gating, and cart preservation
