long window: count where op with a rows bucket based pre-agg table may produce incorrect result

**Describe the feature you'd like**

```sql
deploy dp options (long_windows = 'w1:3')
select count_where(.....
```

`3` as a rows based bucket size, since there is a extra filter key for pre-agg table added, rows in pre-agg table, where their
ts_begin and ts_end value, are not aligned.

currently, this op (`*_where with rows bucket`) is turned off in #2255 -> compile time error

**Additional context**

Add any other context or screenshots about the feature request here.

The issue mentions a pre-aggregation table with misaligned timestamps causing incorrect results for count_where operations with row-based buckets. Start by examining the code changes in #2255 that disabled this operation. Look for the long window implementation and pre-agg table handling, particularly around filter keys and bucket alignment. Running existing tests related to long windows and pre-agg tables will help understand the failure.
