[Bug]: Adding Content Length Guardrail requires Max word count to set for not enabled path as well.

Description

I only needed to enable content length guardrail for Request path.

But had to set the Max value in the Response Path although the Response Path is disabled.

Otherwise, following error causes policy failure in gateway.

gateway-runtime-1 | [pol] time=2026-03-30T08:16:41.494Z level=ERROR msg="Failed to build policy chain for route, skipping" route=PATCH|/| error="failed to create policy instance content-length-guardrail:v1: failed to create policy instance content-length-guardrail:v1: invalid response parameters: 'max' must be greater than 0"

Steps to Reproduce

Try to add a content length guardrail for request flow.

Severity Level of the Issue

Severity/Critical (Core functionality is broken but there is a workaround. Need urgent attention)

Environment Details (with versions)

No response

Start by reproducing the request-flow content length guardrail configuration described in the issue, then trace the Management API or Portal UI handling of the disabled response path and the gateway policy validation. Done means a request-only guardrail can be created without setting a response max value and the resulting policy builds successfully.
