Tune Cloud Run for SQLite

[legokichi]

Summary

• raise Cloud Run request timeout from 3s to 60s
• keep Cloud Run maxScale at 1 for the local SQLite + Litestream runtime
• keep container concurrency at 128 and leave sqlx pool sizing to its defaults
• remove timeout/concurrency from Terraform lifecycle ignores so Terraform manages them
• remove redundant timeout/concurrency annotations and update stale comments

Validation

• terraform fmt -recursive -check
• terraform validate
• cargo fmt --check
• DATABASE_URL='sqlite://.local/cloudrun-sqlite-settings.db?mode=rwc' cargo test -p db connect_runs_migrations
