Problem Statement

The HTTPRouteSimpleSameNamespace Gateway API conformance test is currently skipped for Hybrid Gateway mode.
This is a core HTTPRoute test that verifies basic same-namespace routing functionality.

Tracked as part of #3134 and #2551.

Proposed Solution

Investigate and fix the root cause preventing this conformance test from passing with Hybrid Gateway,
then remove it from skippedTestsForHybrid in test/conformance/conformance_test.go.

Acceptance Criteria

• Fix implemented
• HTTPRouteSimpleSameNamespace removed from skippedTestsForHybrid
• Conformance test passes for Hybrid Gateway in CI
