fix: drop docker healthcheck so Traefik routes immediately

Traefik docker provider skips routing for containers whose Docker HEALTHCHECK
reports unhealthy. Our /healthz returns 503 if LAPI is unreachable, which left
the container stuck unhealthy and the router never appeared — every request
returned 404 from Traefik.

/healthz still exists for manual probes; Kuma probes via Traefik also still
work.
