fix(httproutes): retarget guacamole-server + openova-flow-server to cilium-gateway in kube-system (Refs TBD-G6, C12-004) (#1692)

On t22 (omantel.biz fresh Sovereign) 2 of 15 HTTPRoutes went
Accepted=False because their parentRef pointed at a gateway that
does not exist on any Sovereign:

  catalyst-system/guacamole-server     -> gateway-system/cilium-gateway
  catalyst-system/openova-flow-server  -> kube-system/catalyst-gateway

The canonical Sovereign Gateway is kube-system/cilium-gateway,
installed by bootstrap-kit/01-cilium.yaml and used by every other
HTTPRoute (catalyst-api, catalyst-ui, marketplace, gitea, harbor,
keycloak, grafana, hubble-ui, openbao, powerdns, tenant-wildcard).
gateway-system does not exist; catalyst-gateway does not exist.

Fixes:

  - platform/guacamole/chart/values.yaml — default
    guacamole.httproute.parentRef.namespace: gateway-system -> kube-system

  - clusters/_template/bootstrap-kit/56-bp-openova-flow-server.yaml —
    flowServer.httproute.gatewayRef.name: catalyst-gateway -> cilium-gateway
    (namespace already kube-system, untouched)

Verified on t22: all 15 HTTPRoutes now Accepted=True after chart bump
+ Flux reconcile.
