[FIX] pivot: carry forward running totals for missing date buckets

Description:

When a measure is displayed as "running total" and the pivot is grouped by a date granularity (month/day/etc), PIVOT.VALUE returned an empty value for a requested bucket that does not exist in the pivot. This happened because the running-total cache only stores values for materialized pivot buckets, so a missing date key had no direct lookup.

With this commit, for date/datetime dimensions, we build an ordered index of existing buckets per secondary domain and running-total group, and use a binary search to find the nearest previous bucket. If found, we return its cumulative value (carry-forward); if the requested bucket is before the first one, we return empty.
