"""Add metered_stripe_meter_id to subscription_plans (Stripe Billing Meter API).

Revision ID: 030
Revises: 029

Stripe API 2025-03-31.basil+ requires metered prices to be backed by a Meter object.
The meter_id is created by the sync service and stored here so usage reporting can
derive the event_name without an extra API call.
