}
Returns the team’s credit transactions in reverse-chronological order. Every debit (image/video generation, render) and credit (monthly reset, refund, coupon claim, top-up) is a row. Useful for building a usage dashboard, reconciling end-of-month spend, or surfacing “why did my balance drop?” to the user. Scoped to the team selected by the caller’s session / API key. RLS already enforces team membership.
