Migrate LMS/Squeezelite addon; fix is_service_enabled dead pre-check; bump to v2.9.0

New menus/addon_lms_squeezelite.sh: install/reconfigure/uninstall for an
LMS (Lyrion/Logitech Media Server) server and a Squeezelite player,
wired into install.sh's Addons menu. Squeezelite's own start script and
systemd unit now go through $BIN_DIR/$SYSTEMD_DIR like every other
addon instead of hardcoded /usr/local/bin and /etc/systemd/system; LMS's
own apt repo/GPG key/ufw rules stay at their real fixed system paths,
same approach as CUPS.

Fixed a real unguarded-pipeline bug from the legacy install_lms():
`sudo systemctl enable "$service_name" 2>&1 | tee ...` made the exit
status depend on tee (always 0) instead of systemctl enable, silently
swallowing real enable/start failures. Now uses enable_and_start_units().

Fixed is_service_enabled() (shared helper, backported into the legacy
script too): its list-unit-files pre-check never matched a bare service
name, so it always fell through to "not enabled" regardless of the real
state. Dropped the dead pre-check.

Full command-level stubbed test suite covering install/reconfigure/
uninstall for both LMS and Squeezelite, including the repo-vs-fallback-
download path, undetectable-service-name path, and enable/start-failure
path. Full 12-suite regression + real end-to-end menu navigation via
install.sh all pass.

+**Recent Updates (v2.9.0):**
+- **LMS Server / Squeezelite Player migrated** — install/reconfigure/uninstall for both, in `./install.sh`. Squeezelite's own start script and systemd unit now go through `$BIN_DIR`/`$SYSTEMD_DIR` like every other addon instead of hardcoded `/usr/local/bin`/`/etc/systemd/system`; LMS's own apt repo/GPG key/ufw rules stay at their real fixed system paths, same approach as CUPS.
+- **Bug fix:** the legacy `install_lms()` enabled/started the detected service via `sudo systemctl enable "$service_name" 2>&1 | tee /tmp/lms-enable.log` — piped through `tee`, the statement's exit status reflected `tee` (always 0), not `systemctl enable`, so a real enable/start failure was silently swallowed instead of falling through to a warning. Now uses the shared `enable_and_start_units()` helper.
+- **Bug fix (shared, backported to the legacy script too):** `is_service_enabled()`'s pre-check never matched a bare service name against `list-unit-files`' `"$service.service"` lines, so it always reported "not enabled" regardless of the real state. Dropped the dead pre-check — see "Modular Management" below.
+
+**Previous (v2.8.0):**
 - **Remote Access migrated** — VNC, WireGuard, Tailscale, and Netbird, each with its own install/connect/status/uninstall flow. The biggest Addon so far. Tailscale/Netbird install via the vendors' own `curl | sh` method, preserved as-is.
 - **Important framework-level bug found and fixed:** `run_menu()`'s *handler* call has been crash-guarded since v2.1.0, but its *status function* call was still completely bare. A status function is meant to be read-only display, but a pipeline whose `grep` matches nothing (which `pipefail` turns into a failure even though the actual last command succeeds) would crash the **entire session**, not just fail to show status. Found while building `wireguard_status()` and verifying its exact failure mode rather than assuming it was covered. Fixed once, in the framework, protecting every status function across every menu — present and future. Also audited every existing status function for the same shape and fixed one real instance in `power_schedule_status()`.
 - Deduplicated: promoted `power_schedule.sh`'s `enable_and_start_timers()` to a shared `enable_and_start_units()` in `lib/menu.sh` (works for services now, not just timers) rather than writing the same helper a second time for VNC/WireGuard.

+# RELEASE v2.9.0 - LMS Server / Squeezelite Player Migrated;
+#                   is_service_enabled() Dead Pre-Check Fixed
+# - New in ./install.sh: LMS Server / Squeezelite Player
+#   (menus/addon_lms_squeezelite.sh) - install/reconfigure/uninstall for
+#   an LMS (Lyrion/Logitech Media Server) server the kiosk can host, and
+#   a Squeezelite player the kiosk can run against any LMS server on the
+#   LAN. Squeezelite's own start script and systemd unit now go through
+#   $BIN_DIR/$SYSTEMD_DIR (lib/config.sh) instead of hardcoded
+#   /usr/local/bin and /etc/systemd/system, matching every other addon;
+#   LMS's own apt repo/GPG key/ufw rules stay at their real fixed system
+#   paths, same as CUPS.
+# - Fixed a real unguarded-pipeline bug from the legacy install_lms():
+#   `sudo systemctl enable "$service_name" 2>&1 | tee /tmp/lms-enable.log`
+#   made the whole statement's exit status depend on `tee` (always 0)
+#   instead of `systemctl enable`, so a real enable/start failure was
+#   silently swallowed rather than falling through to a warning. Now
+#   uses the shared enable_and_start_units() helper instead.
+# - Fixed is_service_enabled() (shared by both scripts): its pre-check
+#   `systemctl list-unit-files | grep -q "^${service}\s"` never matched,
+#   since every call site passes a bare service name (e.g.
+#   "squeezelite") while list-unit-files lines start with
+#   "squeezelite.service" - so the function always fell through to
+#   `return 1` regardless of the real enabled state. `systemctl
+#   is-enabled` already reports "not found" as a failure on its own, so
+#   the dead pre-check is simply dropped. Backported here since it's the
+#   same shared function in both scripts and the fix is low-risk
+#   (behavior-preserving for every state except the one it was silently
+#   getting wrong).
