v0.327.1: files.<domain> reaches FileBrowser again — a file route by name, not Docker labels

v0.327.0's box walk: files.<domain> timed out on demo-hp and the N100. With labels, Traefik kept the address it chose at
container start (on felhom-filebrowser, before the gate joined traefik-public). FileBrowser now carries no Traefik
labels; dynamic/filebrowser.yml routes files.<domain> to http://filebrowser:80 by name, resolved per connection and
only while the gate keeps it on traefik-public. Test extended, red-proved.

 > **Mount prerequisite (Section-G):** the controller writes these stacks under `/opt/docker/stacks` *inside its container*, but `docker compose up` runs on the **guest** Docker daemon. The golden's controller-bootstrap (`felhom-agent` `build-golden.sh`) therefore bind-mounts that path **same-path** (`-v /opt/docker/stacks:/opt/docker/stacks`) so the daemon resolves every relative bind source — without it, all bind-mounted stacks (base infra and customer apps) silently break.

 **Controller routing + the wildcard cert anchor (`wireController` → `RenderControllerRoute`, v0.41.1 / v0.42.1).** filebrowser self-registers with traefik via Docker labels + `traefik-public` membership baked into its compose; the controller can't (it's started by the golden bootstrap *before* `traefik-public` exists, and the v2 `bootstrap.json` carries no domain — that comes from the hub pull). So `EnsureBaseStack` wires the controller **post-pull**: it `docker network connect traefik-public felhom-controller` and writes a traefik file-provider route `dynamic/controller.yml` (`Host(felhom.<domain>) → http://felhom-controller:8080`, write-if-changed). When DNS-01 ACME is configured, that route is **also the wildcard-cert anchor**: its router-level `tls.domains: *.<domain>` makes traefik **proactively obtain the wildcard `*.<domain>` + apex via Cloudflare DNS-01 at startup** (an entrypoint-level `http.tls.domains` does *not* trigger issuance in traefik v3 — only a router-level `tls.domains` does). Every other router then serves that one real wildcard cert by SNI — no per-app `certresolver` labels. This is what lets a LAN client reach the box directly at `*.<domain>` with the real cert (the `felhom-agent` split-horizon resolver depends on it).
