Fringg b5471b7720 perf: add covering indexes for referral network queries
Add composite indexes on advertising_campaign_registrations(user_id,
created_at) and transactions(user_id, type, is_completed, amount_kopeks)
to enable index-only scans. Uses CREATE INDEX CONCURRENTLY for zero
downtime. Also enable transaction_per_migration in Alembic env.py.
