GatewayAPI: Fix listener parsing

[Managarmrr]

Previously, parsing the listeners of a Gateway object only worked correctly, if only one listener of a given type (HTTP or TLS) was present, as looping over them was incorrectly handled.

Fixes: #27533
Fixes: 677e8b4 ("Implement TLSRoute")

Fix Gateway managed services not exposing all ports

Hi @Managarmrr , thanks for the contribution. I can't speak for the details, will leave review up to the assigned CODEOWNERS. But I will point out one thing - Cilium relies on linear git history, so before accepting this PR the merge commit will need to be dropped. Consider either rebasing against tip of main + force pushing the PR to update, or use the drop-down from "update branch" at the bottom of the page to do a rebase against the main branch.

I've kicked off the initial testsuites to give CI feedback for now.

Thanks for the heads up, for some reson I expected GitHub to perform a rebase on main when I pressed that button. Fixed it now.
