next dev bound to 0.0.0.0:3000 with the host source dir bind-mounted
rw was the entry point malware kept getting dropped through (see
prior commit). Now builds and runs `next start`; the bind mount is
gone so a compromised container can no longer write onto host disk.
Also bumps next to 15.1.11, patching CVE-2025-66478 (critical RCE via
the RSC Next-Action header) and the follow-up CVE-2025-67779/55184/
55183 batch — the installed 15.1.6 was vulnerable to all of them and
is the likely actual initial-access vector.

The frontend container ran `next dev` bound to 0.0.0.0:3000 with the
host source directory bind-mounted rw into it. Over months this let
attackers write files directly onto the host filesystem, which then
got swept into git by an unrelated Gitea ZIP restore. Removes 4 UPX-
packed ELF binaries and a defacement marker (cox.txt/html).
