Перевести FakeTenantLimitStore на NSubstitute

Хелпер Support/TestTenantLimitStore: строки лимитов с полной бюджетной
семантикой (GetOrCreate/GetState/AddUsage/UpdateBudget, Warned80/
NotifiedExhausted, сброс истёкших периодов, сценарий сбоя чтения), DI получает
.Store. Потребители (13 файлов) перетипизированы, фейк удалён,
тесты 1340 зелёные.
