Move AI document parsing toggle from Config to Filtering tab

Removes duplicate: the setting was in Config tab (General Settings) AND
inside Advanced Settings in the Filtering tab. Now it lives only in the
Filtering tab as a prominent standalone toggle, since it's directly
related to AI filtering behavior.
