chore(deps): bump pgsql-parser stack to latest published versions

[pyramation]

Summary

Propagates the latest pgsql-parser stack (with the recent deparser round-trip fixes, incl. MergeWhenClause support and SecLabelStmt qualified-name fixes from constructive-io/pgsql-parser#301–#304) across the workspace, so pgpm and all parser consumers pick up the corrected parse/deparse behavior:

• pgsql-parser ^17.9.15 → ^17.9.17
• pgsql-deparser ^17.18.3 → ^17.18.5
• @pgsql/utils ^17.8.17 → ^17.8.19

Consumers updated (found via makage update-deps --from pgsql-parser): pgpm/core, pgpm/cli, postgres/pg-ast, postgres/query-builder, packages/safegres, packages/csv-to-pg, packages/node-type-registry, graphile/graphile-sql-expression-validator. Lockfile regenerated with pnpm 10.

Verified locally: full workspace build passes; test suites for pgpm/core (373), pg-ast, query-builder (111), graphile-sql-expression-validator (271) all green.
