[PHP] Run Blueprint tests with the current SQLite release

[adamziel]

Blueprint step tests now install and run against the current SQLite Database Integration release instead of version 2.2.23.

The fixture uses RunnerConfiguration's unversioned plugin URL, which currently serves 3.0.0. SQLite 3.0 requires a non-empty DB_NAME, defaults to WAL journaling, and blocks older bundled SQLite versions unless the documented compatibility constant is set. The fixture therefore supplies DB_NAME in its minimal configuration files and declares SQLITE_JOURNAL_MODE=DELETE plus WP_SQLITE_UNSAFE_ENABLE_UNSUPPORTED_VERSIONS=true. Tests which replace wp-config.php retain those database settings.

NewSiteResolver applies Blueprint constants before core installation opens the database connection. The normal constants step still runs later and remains idempotent. The SQL error test also puts its successful setup query and failing query on separate lines, matching RunSqlStep's line-by-line execution.
