fix: skip cloud-init wait in Hetzner Docker mode (#2924)

Hetzner's waitForReady() was missing the useDocker check that GCP
already has. Non-minimal agents (openclaw, codex) with --beta docker
waited 5 minutes for a cloud-init marker that never appears on Docker
CE app images.

Adds useDocker to the condition and a source-level regression test
verifying both Hetzner and GCP include the check.
