admin 22fa01b716 audiobookshelf: remove the client-written X-Forwarded-For chain on its router (R-753)
request-ip — leftmost XFF; its auth limiter (40/10 min) is keyed by IP only. Once traefik trusts the tunnel's fixed address (controller v0.286.0), the leftmost entry is what a
stranger writes; with the chain removed the app reads traefik's X-Real-Ip or its peer, as before — never forgeable.
Measured on 9202: a router with this middleware receives no X-Forwarded-For (felhom.eu audits/visitors-2026-10-01/A/P1).

# Run-identity: ROOT (fallback). user "1000:1000" was tried but the image creates its /metadata named
# volume as root at init and fails (`EACCES mkdir /metadata/logs`) when pinned to 1000. So it runs as
# root and relies on the setgid 2775 userdata dirs (files land group 1000 → FileBrowser can browse/read).
# (Verified live; see REPORT.)
