"""fc3b: app_setting key/value table

Revision ID: 0012
Revises: 0011
Create Date: 2026-05-20

A simple key/value table for small app settings that don't fit
ImportSettings. Initially seeds only `extension_api_key` (done in
create_app on first boot — not in the migration, to keep it
deterministic and independent of randomness).
