feat(capi-cluster/hetzner): CAPH v1.1.7, Ubuntu 26.04, hrobot provider IDs

- Bump global.caph.version v1.1.3 -> v1.1.7 (latest; bugfixes + additive v1beta2 conditions, no breaking changes).
- Default the Hetzner OS image to Ubuntu 26.04: bare-metal installImage -> Ubuntu-2604-resolute-amd64-base.tar.zst (matches kubeaid-cli's default), hcloud imageName -> ubuntu-26.04.
- Enable the canonical hrobot://<server-id> provider-ID format for bare-metal nodes via the capi.syself.com/use-hrobot-provider-id-for-baremetal annotation on the HetznerCluster (bare-metal/hybrid modes). Aligns CAPH's Machine providerID with what the upstream Hetzner CCM (robot support) writes to Node.spec.providerID. Affects newly-provisioned machines only.
