Drop the Flux UI addon and its Tailscale exposure because the UI lags the
current Flux APIs and reports misleading HelmRelease errors. Keep Flux managed
through the controllers themselves and use Rancher or the flux CLI for access.
Replace Ansible port-forwarding + tailscale serve with direct Tailscale LB
services matching the existing Rancher pattern. Each service gets its own
tailnet hostname (grafana/prometheus/flux.silverside-gopher.ts.net).
