test(pgpm): update init snapshots for workspace-level safegres boilerplate

[pyramation]

Summary

Snapshot-only update for constructive-io/pgpm-boilerplates#52, which moves safegres from every pgpm/module to the workspace root: safegres.config.js / safegres-perf-baseline.json now appear once at <workspace>/ instead of under each packages/<module>/, and the module package.json no longer carries audit:db* scripts or the safegres dep.

Affected: init.test.ts.snap, init.install.test.ts.snap, extensions.test.ts.snap. Regenerated by temporarily pointing withInitDefaults at the local boilerplate branch, then restoring repo/fromBranch to the real defaults in the snapshot (no source changes).

Landing order. pgpm/cli/test-utils/init-argv.ts scaffolds from the boilerplates repo at fromBranch: 'main' (not a pinned ref), so these tests track that repo live. Merge constructive-io/pgpm-boilerplates#52 first; until then this PR's pgpm/cli tests fail (old template), and after it merges main here fails until this lands.
