Add index on plan_recommendations.recommendation_id to Drizzle schema

Browse source 
Plan deletes cascade to recommendation rows, and each cascaded delete
fires an FK check against plan_recommendations.recommendation_id. With
~26M rows and no index on that column the check seq-scans per row,
making any plan deletion path time out.

The index already exists on the live DB (created CONCURRENTLY on
2026-07-02 as idx_plan_recommendations_recommendation_id, 74s build);
this brings the Drizzle schema in line so it stops drifting. No
migration is included — generating/applying it is left as a human
action, and it must reuse the existing index name (IF NOT EXISTS) so
it no-ops against prod.
