fix(cubestore): Фvoid empty SortPreservingMerge for empty sort_on (#1…
c7d3ad1 
…1160)

A rolling-window pre-aggregation joins a generated time-series with the
rollup table on an inequality (and, under Tesseract, scalar window-bound
subqueries), which lowers to a join with an empty equi-join `on`. The empty
`on` propagates as an empty `sort_on` to the index scan, which then builds a
SortPreservingMergeExec with no sort expressions. Under DataFusion 46 such a
merge errors at execution with "Sort expressions cannot be empty for streaming
merge" once a worker has more than one partition to merge.
