 * Translates the `budget_type` and `status` query params into real
 * `campaign` constraints, mirroring the admin campaigns middleware:
 * `budget_type` is resolved through the `campaign_budget` link (never a
 * nested relation filter) and `status` becomes a null-aware date range.
 * Both are appended to `$and` so the seller link filter is preserved.
