resetDb() DROPs schema; dev DATABASE_URL pointed at the shared prod void DB on
.215. setup.js now forces a dedicated void_test DB (TEST_DATABASE_URL or derived)
and throws if it would target prod. Created void_test + pg_hba rule on CT 310.
Verified: full suite green, prod void space count unchanged (2→2).
