A missing Sentry DSN meant "no error tracking configured yet," not "the API should refuse to start" — but env validation treated it as the latter, hard-failing startup in production if it wasn't set. Sentry initialization was already conditional on SENTRY_DSN being present (src/main.ts), so this only affects the boot-time validation gate, not whether Sentry actually turns on when configured.
