coder: desktop template (KasmVNC + dotfiles) for the homelab cluster

Kubernetes template for coder.nic-oconnor.com: an XFCE desktop served by
the KasmVNC module, with this repo applied by the dotfiles module. Home is
a truenas-iscsi PVC so $HOME tools and op.env survive stops.

Pinned to enterprise-desktop:ubuntu-noble + KasmVNC 1.5.0 because the
plain `ubuntu` tag is now resolute, which KasmVNC has no package for.
Path-based app (no wildcard access URL). An ephemeral 1Password token
parameter lets bootstrap's secrets module run unattended on first start.
