CRITICAL FIX: remove description field from app_settings inserts

Production failing with "column description does not exist" error.
The app_settings table only has: id, setting_key, setting_value, setting_type, updated_at
Removed all description fields from migration 032.

URGENT: Production is down - this is blocking the backend from starting.
