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.

+- **Regression in v0.327.0, found by its own box walk:** on demo-hp and the N100 (demo-felhom) `files.<domain>` timed
+  out, through Traefik and over the public address, while FileBrowser sat on `traefik-public` (Tester 1 and 9202 worked).
+  With Docker labels, Traefik chose FileBrowser's address once, when the container started — on `felhom-filebrowser`,
+  before the box joined it to `traefik-public` — and the later network connect did not refresh it (it did on two boxes
+  only by the chance of a later health event). Now FileBrowser carries NO Traefik labels; `files.<domain>` is a
+  file-provider route (`dynamic/filebrowser.yml`, `infra.RenderFileBrowserRoute`) to `http://filebrowser:80` by NAME,
+  resolved per connection, and only while the R-1126 gate keeps FileBrowser on `traefik-public`. Every box recreates
+  FileBrowser once more (the compose changed). `TestFileBrowserRender_R1126_NotPublicAtStart` now also refuses any
+  Traefik label and checks the route, red-proved.

 ## v0.327.0 — FileBrowser is published only after its default login is checked; the install check uses real memory amounts and says what to do (2026-10-17)
