Add flexible DNS management to Docker Watcher. By default, wildcard DNS is assumed (current behavior). When disabled, users can configure a Cloudflare DNS provider with API token and zone selection. DNS A records are automatically created/updated/deleted in sync with proxy consumers (deployed instances and standalone proxies). - Settings: wildcard_dns toggle, dns_provider, cloudflare credentials - Cloudflare client: Provider interface with EnsureRecord/DeleteRecord/ListRecords - DNS lifecycle hooks in deployer and proxy manager (best-effort) - Settings UI: DNS config section with provider picker, zone selector, test button - DNS Records page at /dns with filtering, sync status, reconciliation - Records visible in both wildcard and managed modes - Cleanup on provider change: removes old records when switching modes
