fix(api-service): Idempotency cache key user API fixes NV-7060

[scopsy]

What changed? Why was the change needed?

This PR resolves the InternalServerErrorException: Cannot build idempotency cache key without user (NV-7060, Sentry Issue: API-HM).

The IdempotencyInterceptor.isEnabled() method incorrectly returned true when the authentication scheme was not API_KEY, leading to getCacheKey() being called without a user.

The changes include:

• Corrected the isEnabled() logic to return false when the auth scheme is not allowed, preventing idempotency from being enabled for non-API_KEY requests.
• Added defensive checks in both isEnabled() and intercept() methods to gracefully skip idempotency if a user is not present, preventing the InternalServerErrorException.
