fix(mavvrik): replace dus.* with explicit column list in exporter query

Mirrors the approach used by CloudZero's integration — select only the known
columns from LiteLLM_DailyUserSpend rather than SELECT *. This avoids
returning the full token hash via a wildcard and keeps the query well-defined
regardless of future schema changes to unrelated columns.
