Claude fa906186c3 fix(services): conditional caddy_net across all Docker service scripts 
Only include the caddy_net network block in generated docker-compose.yml
files when ~/docker/caddy exists. Prevents "network caddy_net declared
as external, but could not be found" on standalone installs without Caddy.

Affected: actualbudget, archivebox, arm, audiobookshelf, calibre-web,
changedetection, drum-rhythm-game, emby, fmd, frigate, frigate-audio,
frigate-notify, gatus, homeassistant, immich, iopaint, jellyfin, joplin,
koha, lyrion, magicmirror, mail-archiver, mattermost, mealie, meshcentral,
n8n, nextcloud, ntfy, onlyoffice, portainer, stirling-pdf, syncthing,
traccar, unifi, uptimekuma, vaultwarden, wg-easy

Skipped: authelia (creates caddy_net itself), caddy, crowdsec, wolf,
wolf-pair, and services using network_mode: host with no caddy_net.

#
# Ported from ubuntu-post-install-24.04-crowdsec.sh (# ---- A.R.M. ----).

# A.R.M. (Automatic Ripping Machine)
Auto-rips DVDs, Blu-rays, and CDs when you insert them — identifies the disc,
fetches metadata, and transcodes to a usable format.
- Web UI: http://localhost:8080 (complete setup on first visit)
- Ripped output: \`$ARM_OUTPUT\` → movies and music subdirs
- App data: \`config/\` and \`logs/\`
## Manage
\`\`\`bash
cd $ARM_DIR
docker compose up -d # start
docker compose down # stop
docker compose logs -f # logs
docker compose pull && docker compose up -d # update
\`\`\`
## Adding optical drives
Edit \`docker-compose.yml\` and add more \`devices:\` entries:
\`\`\`yaml
devices:
- /dev/sr0:/dev/sr0
- /dev/sr1:/dev/sr1
\`\`\`
Then \`docker compose up -d\` to apply.
## Notes
- First launch: open the web UI and complete the setup wizard.
- \`privileged: true\` is required for ARM to control the optical drive.
- Change the output path in \`.env\` (\`ARM_OUTPUT=\`), then \`docker compose up -d\`.
