Two issues caught in a real-client smoke run against the freshly
bootstrapped DB:
1. NRE in ShadowverseTranslationMiddleware for parameterless actions.
Five new actions (Sleeve.Info, LeaderSkin.{Ids,Products},
ItemPurchase.Info, SpotCardExchange.Top) took no parameters, but
the middleware does
`endpointDescriptor.Parameters.FirstOrDefault().ParameterType`
to discover the request DTO — `FirstOrDefault` returns null on a
zero-param action and `.ParameterType` NREs. Tests didn't catch it
because the test client POSTs plain JSON, bypassing this path.
Fix: each action now takes `BaseRequest _` matching the codebase
convention (PuzzleController.Info, BattlePassController.Info, etc.),
plus the middleware throws an actionable
InvalidOperationException pointing at the convention so the next
contributor doesn't repeat the mistake.
2. Leader-skin set sale showed up as "FREE / Claim" with empty
Includes panel after the viewer bought every skin in a series
with no configured bonus items. Root cause: ComputeRewardStatus
emitted status=1 (not_got) when set_sales_status != 0 regardless
of whether rewards.items was empty, and SkinPurchaseInfoTask.
CreateSetSaleInfo flags `is_free=true` on (is_completed &&
not_got). Prod ships status=0 when items is empty even with
set_sales_status==1 — we now mirror that.
504 tests still pass.
