r-dash-postgres-integration-tests-skip-on-creds

Integration tests that require a live Postgres connection auto-skip or error with a DB auth/creds mismatch when run outside make up. This is a pre-existing environment issue (not a Wave 3 regression): 54 integration errors all share the same Postgres credentials failure mode. The 133 DB-free tests are the reliable CI signal; integration tests require make up with seeded Postgres to run.
