fix(signoz): fix ClickHouse hostname resolution and IPv6 binding

- Override the ClickHouse image's config.d/docker_related_config.xml,
  which listens on the IPv6 wildcard address ([::]) first and fails to
  bind on hosts without IPv6 support; listen on 0.0.0.0 (IPv4) only and
  disable the internal DNS cache so transient startup DNS failures for
  zookeeper-1/clickhouse are not cached (issue #534).
- Set hostname: clickhouse (instead of container_name) so the server
  identifies itself as the cluster host declared in cluster.xml.
- Remove the explicit signoz-net network: Dokploy attaches its own
  networks automatically and the repo validator rejects explicit
  networks; a fixed-name shared network also breaks service DNS across
  deployments.
- Fix mount mismatch: template.toml created files/signoz/prometheus.xml
  while the compose mounts ../files/signoz/prometheus.yml, so Docker
  silently mounted a directory as the signoz prometheus config.
- Give the otel-collector domain its own generated host: both domains
  previously shared the same host and path "/", creating two conflicting
  Traefik routers where one service randomly won.

Closes #534
