🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Isolate this fallback test from all DevPass overrides.

The new loop calls getBaseLimit(config, "dev"), which honors GATEWAY_RATE_LIMIT_DEV_<KEY>_RPM. The cleanup list at Lines 60-70 only names GATEWAY_RATE_LIMIT_DEV_CHAT_COMPLETIONS_RPM. If another path override is present in the test process, this test fails even when the fallback calculation is correct. Clear every DevPass override before this assertion, or run the assertion with a controlled environment.

In `@apps/gateway/src/lib/org-rate-limit.spec.ts` around lines 322 - 326, Isolate
the test around getBaseLimit from environment-specific DevPass overrides by
clearing or controlling every GATEWAY_RATE_LIMIT_DEV_<KEY>_RPM variable for all
entries in PATH_RATE_LIMITS before asserting the fallback values. Keep the
existing loop and expected defaultRpm * 2 behavior unchanged.

P2 Badge Update the documented DevPass overrides

When an operator copies or uncomments the DevPass settings in .env.example:121-132, every listed GATEWAY_RATE_LIMIT_DEV_* value remains 120; getRateLimitEnvNumber gives those values precedence over this new fallback, so the deployment silently retains the old limits instead of receiving the intended per-endpoint increase. Update the sample comments and values to match the new defaults.
