feat: inline domain health checks and improve address UX

- addPublicDomain returns DNS query + port check results (AddPublicDomainRes)
  so frontend skips separate API calls after adding a domain
- addPrivateDomain returns check_dns result for the gateway
- Support multiple ports per domain in validation modal (deduplicated)
- Run port checks concurrently via futures::future::join_all
- Add note to add-domain dialog showing other interfaces on same host
- Add addXForwardedHeaders to knownProtocols in SDK Host.ts
- Add plugin filter kind, pluginId filter, matchesAny, and docs to
  getServiceInterface.ts
- Add PassthroughInfo type and passthroughs field to NetworkInfo
- Pluralize "port forwarding rules" in i18n dictionaries
