- Add pgbouncer service to docker-compose-dev.yml with dev config
- Route DATABASE_URL through pgbouncer:6432 in dev (matches prod)
- Add PgBouncer pools and stats tables to /admin/infra with color-coded
avg query/xact times and client waiting indicators
- php, messenger, cron now depend on pgbouncer instead of database directly
