Claude bec9228c55 Back up existing files before every service overwrites them
Confirmed live: install_frigate()'s fresh-install path overwrote a
working, hand-crafted docker-compose.yml (Frigate + mosquitto +
frigate-notify) with zero backup, because that file's shape didn't match
what frigate.sh's own "existing install" detection knew how to recognize.
Every service's own detection is a judgment call about what counts as
"already installed" and can miss a real setup built outside this repo's
conventions.

lib/common.sh gains backup_if_exists(FILE) — copies FILE to
FILE.bak.<timestamp> if it exists, no-ops otherwise (including DRY_RUN).
Applied before every service's own `cat > docker-compose.yml`/`cat > .env`
write across all 60 services that do one (115 call sites), plus a matching
standalone-mode stub added to every service's own bootstrap block, same
convention already used for port_in_use/find_free_port. This doesn't
replace a service's own update/fresh-reinstall detection — it's the safety
net underneath it, so a wrong detection costs a .bak file to restore from
instead of the original silently disappearing.

Also fixes the actual gap that surfaced this: services/frigate.sh's
Authelia offer only checked for Authelia installed locally on Frigate's
own box, which is never true for a dedicated NVR box with no local Caddy
either (the common shape — Caddy lives elsewhere, snippet-generation mode
already handles that). Now offers Authelia protection unconditionally and,
when Authelia isn't local, asks whether it lives on the same machine as
Caddy (still "import authelia", since that's local to wherever Caddy ends
up) or on a genuinely separate third machine (the explicit
header-pinned forward_auth form, per CLAUDE.md's "forward_auth to a remote
Authelia" note, needed because a bare authelia:9091 shortcut only works
one hop).

## Music-only setup (per-user library access)
This mount is meant to hold only your music library — which library types
you actually add still happens in Emby's own first-run setup wizard, not
this script (Emby has no compose/env flag for "music-only"; it's a web-UI
step):
1. Open http://localhost:${WEB_PORT} and complete the setup wizard.
2. When adding a library, choose type **Music**, point it at \`/media\`,
and don't add any Movies/TV/other library types.
3. **Per-user library access** (the reason to pick Emby over a Squeezebox
setup for this role): Dashboard → Users → select a user → **Access** tab
→ under "Library Access", uncheck "Enable access to all libraries" and
pick only the libraries that user should see. Repeat per user. New users
default to full access, so revisit this each time you add one.
4. Casting to Chromecast/other cast targets works out of the box from
Emby's own apps — nothing to configure here for that.
Emby is a generalist media server, not a purpose-built music server — for
an always-on background/kiosk audio zone, a dedicated Squeezebox setup
(\`lyrion\`, with \`squeezelite\` as the player) is the more solid choice;
use this Emby instance for browser-based, per-user-restricted access
instead of as the primary always-on player.
