chore(kube): bump chart Helm release stalwart to v0.7.18

- Pin gateway image to immutable tag 2026.9.3: the stale node-cached
  'latest' (old build, state schema v1) crash-looped against the PVC's
  DB already migrated to schema v15/16.
- Add fix-data-owner init container: the operator mounts the PVC root
  at /home/openclaw/.openclaw with fsGroup only, leaving the mount root
  owned by root; OpenClaw >= 2026.9 fchmods its config dir on write and
  fails with EPERM (paperclipinc/openclaw-operator#607).
- Ran one-time 'openclaw doctor --fix --non-interactive' against the
  PVC to complete the 2.0 workspace-state migration.
