fix: fresh PostgreSQL install with DATABASE_SCHEMA fails to start

Browse source 
With DATABASE_SCHEMA set, Open WebUI read its tables from that schema, but the database migrations still created every table in the default public schema. A fresh install then stopped at startup with relation "<schema>.config" does not exist, unless the database user's search_path already put that schema first. The migrations now create their tables, including the migration history, in the configured schema, so a fresh install starts normally.

Fixes #31526
