Fix column name mismatch after copier template update

The subscriptions table still had paddle_subscription_id but the new
code references provider_subscription_id.  Renamed the DB column and
updated all queries in billing/routes.py to match.

Also removed unused get_subscription import from dashboard/routes.py.
