[Fix] Move nresults_postfilters recording to after POST_FILTERS stage

This fixes an issue where composite rules depending on statistics symbols
(like BAYES_SPAM) would fail to trigger. The nresults_postfilters counter
was being set too early (after COMPOSITES stage), preventing detection of
symbols added during autolearn or other post-filter processing.

Fixes #5674
