"""Add name and apprise_url columns to notification_configs

Revision ID: 0001
Revises:
Create Date: 2026-03-26

These two columns were added to the NotificationConfig ORM model in the
Apprise alerting feature PR.  SQLAlchemy's create_all() does not ALTER
existing tables, so deployments that had notification_configs created before
this change are missing the columns and raise a ProgrammingError at runtime.

Using ADD COLUMN IF NOT EXISTS makes this migration idempotent – it is safe
to run against both fresh installs (where create_all already created the
columns) and existing deployments (where the columns are absent).
