Returns the next active beta-refill survey the user has not yet completed.

Ordered by Id ASC (so prod adds new surveys at the tail of the rotation by simply inserting them with the next Id). When all surveys in the pool are completed, returns 404 — the Marketplace then hides the refill prompt entirely until an admin adds another survey to the rotation. Pool membership is controlled by Survey.Category; to retire a survey from the rotation, change its Category or set IsActive=false.
