fix(devcontainer): bake wg + qrencode into the image instead of splitting the VPN procedure across host and container
Operator correction: "sop, wg, and any other tool requirement is supposed to be
baked into the devcontainer."

My previous commit discovered that `wg` existed only on the host, `sops` only in
the container, and `qrencode` on neither -- and fixed it the wrong way, by
splitting every step of the key procedure across the boundary and telling the
operator to `dnf install qrencode` on their workstation. That breaks CLAUDE.md §5
and the devcontainer README's "Don't install the toolchain on the host", produces
a procedure that cannot be reproduced in CI, and is miserable to follow.

wireguard-tools + qrencode are now distro packages in the Containerfile. Both are
in Fedora 44's repos (wireguard-tools 1.0.20260223 -- the same upstream version as
the image this component runs -- and qrencode 4.1.1), unpinned like every other
dnf package there: the pinned thing is the Fedora base, and neither is a gate tool
whose version changes what green means.

Three things got SIMPLER rather than merely relocated, which is the tell that the
rule was right:

  * Step 2 is one pipeline in one shell -- `sops set ... "$(wg genkey)"` writes the
    key straight into the already-encrypted document. No staged copy in .cache, no
    `*.key`-suffix warning, no sha256 comparison to prove the right bytes landed.
  * new-peer.sh derives the server public key from wg-server-key.sops.yaml itself
    (`sops -d --extract | wg pubkey`), so there is no local key copy to keep in
    step with the encrypted one, and no magic host path it must live at.
  * `.cache/` is gitignored at the repo root (mirroring infra/ansible/.gitignore),
    giving the container a persistent non-committable scratch dir. new-peer.sh
    writes profiles to .cache/wg-peers/ -- necessary because the repo bind-mount is
    the container's only persistent read-write mount, so a profile in /tmp there is
    gone before it can reach a desktop. Its blanket "refuse to write inside the
    checkout" guard is now a `git check-ignore` test of the real property.

Verified by execution, not reasoning: the image rebuilds; wg/qrencode/sops all
resolve in it; `sops -d | wg pubkey` runs in one shell; new-peer.sh refuses the
REPLACE-ME placeholder with an actionable message; and a full run with a throwaway
server key renders a correct profile at 0600 under a 0700 gitignored dir, prints
the QR, and refuses a non-ignored destination inside the repo.
