Follow-up to #449: NODE_ENV=production on dev enabled the default 3/10s sign-in limit, which throttled the 6-worker dev E2E (51 sign-in failures). Relaxed for APP_ENV=dev only; staging/prod unchanged.

Summary by CodeRabbit

• Changes
  • Development environments now allow up to 200 email sign-in requests per 10 seconds. Staging and production retain the default sign-in limit.
  • OTP, password-reset, and magic-link verification limits remain 10 requests per 60 seconds.

Walkthrough

The pull request adds environment-specific authentication rate-limit rules and updates the e2e helper’s check for public default credentials on non-local targets.

Changes: Auth rate limits

Layer / File(s)	Summary
Build environment-specific rate limits apps/backend/src/lib/authAccess.ts, apps/backend/src/lib/__tests__/authAccess.test.ts	buildAuthRateLimitRules returns the existing verification limits and adds a /sign-in/email limit of 200 requests per 10 seconds only for dev. Tests cover dev, staging, production, and an undefined environment.

E2E default credential check

Layer / File(s)	Summary
Check default credentials for target URLs test/e2e/steps/helpers/common.ts	assertDefaultCredentialsOnlyLocal now checks the password against the public default email. It rejects non-local target URLs when the password matches.

Priority: Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Isolate APP_ENV for the undefined-environment test.

When the test process has APP_ENV=dev, passing undefined activates the default parameter and returns the dev rule. The backend test run then fails. (github.com)

Clear APP_ENV for this assertion and restore it afterward, or pass the environment explicitly only when constructing authRateLimitRules.
