fix(ci): set ALLOW_DEV_TEST_ENDPOINTS=true for e2e + visual jobs

Without this flag, server/middleware/03.rate-limit.js applies the
100-req/60s general limit to /api/dev/test-login and trips during
parallel e2e runs. The invite.post.js dev short-circuit also
depends on this env var to skip the Resend call (no RESEND_API_KEY
in CI).
