fix(pgsql-test): add missing csv-parse dependency

Add csv-parse and @types/csv-parse to dependencies to fix TypeScript
compilation errors in src/seed/csv.ts. The csv seed functionality
requires csv-parse but it was not declared in package.json.

Fixes test failures where all test suites failed with "Cannot find
module 'csv-parse'" errors.
