Subject: [PATCH 1/2] Co-locate web service with DB region + harden for
 Supabase pooler

- render.yaml: add `region: oregon` with a note to match the database's
  region (Supabase "West US" = oregon). Without this the web service
  defaults to Oregon while a student's Supabase project may be elsewhere,
  causing slow cross-region queries (observed ~2.5-4.7s vs ~0.3s when
  co-located).
- database.yml: set prepared_statements: false and advisory_locks: false
  for production. Harmless on the Supabase session pooler (5432); prevents
  a silent `db:migrate` hang if a student uses the transaction pooler (6543).
