feat: local tier gateway with PGlite + Gitea-only publishing + repo linking

- Add PGlite (embedded Postgres) for local tier — gateway runs without
  external PG server. Same schema, same Drizzle API, zero module refactor.
- Install wizard now offers tier selection (local vs team).
  Local skips DATABASE_URL/VALKEY_URL, writes mosaic.config.json.
- Comment out npmjs publish step in CI (preserved for future use).
- Revert gateway publishConfig to Gitea registry, include in Gitea publish.
- Add repository field to all 23 publishable package.json files for
  Gitea package-to-repo linking.
