feat(controller/speaker): add BGP LB EIP support via IptablesEIP type=lbSvc

- Extend IptablesEIP CRD with spec.type field; add IptablesEIPTypeLbSvc const
- Add handleAddLbSvcEip: IPAM-only allocation, no NAT GW pod involved
- Add --enable-bgp-lb-eip controller flag (config.EnableBgpLbEip)
- Add LbEipAnnotation (ovn.kubernetes.io/lb-eip) constant
- Add handleAddBgpLbEipService: reads EIP status.ip, writes svc.spec.externalIPs
  and svc.status.loadBalancer.ingress for kube-proxy DNAT
- Add collectSvcBgpPrefixes in speaker: announces LB svc ingress IPs via BGP
- Expose enable-bgp-lb-eip in both Helm charts (kube-ovn, kube-ovn-v2)
- Update generated CRDs (kube-ovn-crd.yaml, install.sh)
- Add unit tests for collectSvcBgpPrefixes

test(controller): add unit tests for handleAddBgpLbEipService

fix(controller): allow EnableLbSvc and EnableBgpLbEip to coexist independently

test(e2e): add bgp-lb-eip e2e test suite
