"""Per-article SEO overrides on FAQs

Revision ID: add_faq_seo_001
Revises: rel_hc_uploads_001
Create Date: 2026-07-25

Adds nullable meta_title / meta_description to faqs so an org can override the
public article page's <title> and meta description instead of always deriving
them from the question and answer excerpt. NULL keeps today's derived behaviour.
