feat(deploy): Jellyfin at home, published through WireGuard (ADR 0032)
The instance serves jellyfin.halkyon.eu and its Caddy proxies through a
WireGuard tunnel to a Jellyfin on the operator's own machine, which dials
out, so nothing names the home network's address and its router opens no
port. compose.jellyfin-home.yaml takes the sidecar's place, with its
site's rules unchanged (jellyfin.caddy's upstream is now a setting), and
leaves JELLYFIN_URL unset, so the instance suggests it only while it
answers.

On the instance's server the tunnel reaches Jellyfin from Caddy alone and
nothing of the host (wg-jellyfin-rules.sh, set and removed with the
tunnel); the CI runner's unit denies it, and CI's Sandbox step fails if a
job reaches it. The home end keeps Jellyfin in WireGuard's network
namespace, its port on the loopback alone. The steps are in
deploy/sidecars/README.md, the rules held by test/deploy/jellyfin_home_test.dart.
