erio	3710bc883b	feat: ErrorPolicySkipped returns 500 instead of upstream status code ... When custom error codes are enabled and the upstream error code is NOT in the configured list, return HTTP 500 to the client instead of transparently forwarding the original status code. This matches the frontend description: "other errors will return 500". Also adds integration test TestCustomErrorCode599 verifying that 429, 500, 503, 401, 403 all return 500 without triggering SetRateLimited or SetError.	2026-02-09 18:10:39 +08:00
