Support implicit PostgreSQL foreign key references

[yzxcj797]

Fixes #669.

Summary

• retry PostgreSQL CREATE TABLE imports that omit referenced columns using a narrowly scoped compatibility marker
• resolve those references to the target table's declared primary key, including ordered composite keys
• parse the original SQL first, preserve original parser errors if compatibility parsing also fails, and leave explicit references and other SQL dialects unchanged
• add regression tests to the Node 20/22 build matrix

Scope and compatibility

This follows the importer's existing ordering and name-resolution behavior: the referenced table must appear earlier in the input, and this compatibility path handles unqualified table names. Explicit REFERENCES table(column) clauses are unchanged.

Testing

• npm test - 3 passed
• npm run lint
• npm run build - passed (existing dependency eval and bundle-size warnings only)
• npx prettier --check .github/workflows/build.yml package.json src/components/EditorHeader/Modal/Modal.jsx src/utils/importSQL/postgres.js src/utils/importSQL/postgresImplicitReferences.js test/postgres-implicit-references.test.js
• git diff --check
