  1. sql_series: optimize memory use for range time series 

    Refactored the series parsing code to avoid intermediate object allocations
and mutations, which make longer time series too expensive. The series
is now constructed in single pass, backfilling null values when needed.

  2. sql_query: apply ad-hoc filters on inner subqueries 

    The ad-hoc filters were previously applied on outer query, not on
inner query over an actual table.
