fix: mount openclaw routes at /openclaw prefix + fix docker.client wrapper + strip duplicate /apps/ paths across sub-routers

- openClawRoutes was mounted at root causing /status vs /openclaw/status mismatch
- ctx.docker is a typed wrapper {client,pull,...} — all calls now use docker.client.*
- templates/deploy/removal/restore sub-routers had /apps/ hardcoded in inner routes
  causing double-stacking when mounted under /apps (→ /apps/apps/templates etc)
- openclaw.js: GET /status, POST /deploy, GET/POST /proxy/*, DELETE /
