Migrate Asterisk Intercom, redesigned as SIP-extension-only; bump to v2.10.0

New menus/addon_asterisk_intercom.sh, wired into install.sh's Addons
menu. The legacy addon offered Client Only (Baresip SIP client), Server
Only, and Full (server + client), where Server/Full downloaded and ran
a third-party installer from a separate "Easy Asterisk" repository to
stand up a whole Asterisk PBX. That repository has since gone through a
major rework upstream, so this migration drops the PBX-install path
entirely: the addon now only installs Baresip and registers this kiosk
as a SIP extension against an Asterisk server the user already has
running elsewhere. It never installs or manages Asterisk itself. The
legacy script's own three-option version is untouched, same as every
other migrated menu.

Dropped the legacy client path's dependency on the Easy Asterisk repo's
GitHub API for version tracking - now reads the real installed baresip
package version via dpkg instead. Added an uninstall option, which the
legacy addon never had at all.

Bug fix found while testing: an unguarded `ver=$(baresip_installed_version)`
assignment crashed the whole session under set -e the first time status
was checked before Baresip was installed (dpkg-query legitimately fails
when the package isn't there). Guarded with `|| true`.

Full command-level stubbed test suite covering configure (manual/auto-
answer, TLS port bump, apt-install failure) and uninstall (keep/purge
config) for both fresh and already-configured states. Full 13-suite
regression + real end-to-end menu navigation via install.sh all pass.

### Installing Easy Asterisk Intercom
### Installing Asterisk Intercom
The Easy Asterisk Intercom addon provides voice communication capabilities to your kiosk system.
The Asterisk Intercom addon connects this kiosk as a SIP extension to an
Asterisk server you already have running elsewhere (your own PBX, a
Docker container, another box on the network - anywhere). It installs
and configures Baresip as that extension; it does not install or manage
Asterisk itself.
**Access the addon menu:**
```bash
./ubuntu-based-kiosk.sh
# Select: 2) Addons
# Then: 4) Easy Asterisk Intercom
git clone https://github.com/outis1one/ubuntu-based-kiosk/
cd ubuntu-based-kiosk
./install.sh
# Select: 2) Addons → Asterisk Intercom (SIP Extension)
```
**Features:**
- **Automatic installation** - Downloads and installs the latest version from the Easy Asterisk repository
- **Update detection** - Checks for newer versions and prompts to update
- **Safe re-runs** - Can be run multiple times without breaking existing configurations
- **Config preservation** - Automatically backs up and restores configurations during updates
- **Full Asterisk PBX** - Complete telephony features including SIP, extensions, voicemail
**What you'll be asked for** (must match what's already configured on
the Asterisk server): server IP/hostname, SIP port (default 5060, or
5061 if you enable TLS), extension number, SIP password, and whether to
auto-answer incoming calls (intercom mode) or ring for manual answer.
**Installation behavior:**
- **First install:** Downloads latest version from https://github.com/outis1one/easy-asterisk
- **Already installed (latest):** Prompts to re-run installation (preserves configs)
- **Update available:** Prompts to update and shows version difference
- **All scenarios:** Configuration files in `/etc/asterisk/` and installation settings are preserved
**Managing Easy Asterisk:**
**Managing the client:**
```bash
# Check installation status
systemctl status asterisk
# Check status (as the kiosk user)
sudo -u kiosk systemctl --user status baresip
# View Asterisk console
asterisk -rvvv
# Restart
sudo -u kiosk systemctl --user restart baresip
# Restart Asterisk
systemctl restart asterisk
# View logs
sudo -u kiosk journalctl --user -u baresip -f
# Configure intercom (rerun installation to update)
./ubuntu-based-kiosk.sh
# Select: 2) Addons → 4) Easy Asterisk Intercom
# Reconfigure or uninstall
./install.sh
# Select: 2) Addons → Asterisk Intercom (SIP Extension)
```
**Installation location:**
- Installation files: `/opt/easy-asterisk/`
- Configuration: `/etc/asterisk/`
- Version tracking: `/opt/easy-asterisk/.version`
- Config backups: `/opt/easy-asterisk/config_backup/`
- Baresip config: `~kiosk/.baresip/` (`accounts`, `config`)
- systemd user unit: `~kiosk/.config/systemd/user/baresip.service`

legacy `ubuntu-based-kiosk.sh` still offers a Server/Full option that
downloads and runs a third-party installer from a separate "Easy
Asterisk" repository - that repository has since gone through a major
rework upstream, so it isn't carried forward into this addon. If you
need a PBX, set one up separately (that same legacy option, a
FreePBX/Issabel image, a Dockerized Asterisk, etc.) and point this
addon at it as a plain SIP extension.

**Previous (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.

# menus/addon_asterisk_intercom.sh - "Asterisk Intercom" addon: connect the
# kiosk as a SIP extension to an *existing* Asterisk server.
#
# The legacy addon offered three options: Client Only (a Baresip SIP
# client - what this file is), Server Only, and Full (server + client).
# Server/Full downloaded and ran a third-party installer from a separate
# "Easy Asterisk" repository to stand up a whole Asterisk PBX. That
# repository has since gone through a major rework upstream, so wiring a
# full PBX install through it here no longer makes sense to maintain -
# and most kiosk deployments don't need this device to *be* the PBX
# anyway. This addon now does only the client/endpoint piece: install
# Baresip and register it as one extension against an Asterisk server
# the user already has running somewhere else. It never installs or
# manages Asterisk itself.
#
# Two other things fixed while narrowing the scope:
# - The legacy client path tracked its own version by calling out to the
# (now-reworked) Easy Asterisk repo's GitHub API and stamping a
# "<repo-version>-client" string in a side file. That coupling is
# exactly what's being dropped, so version tracking now just reads the
# real installed `baresip` package version via dpkg - one less network
# dependency and one less thing to keep in sync with an external repo.
# - The legacy addon had no uninstall option for the client at all -
# added below.
#
# Real system state: apt package, a per-user config directory under
# $KIOSK_HOME, and a systemd --user unit for $KIOSK_USER (not a system
# service - Baresip needs the desktop session's PulseAudio/PipeWire
# socket). Every write goes through `sudo`/`sudo -u "$KIOSK_USER"`, all
# stubbed at the command level in tests - there's no real D-Bus user
# session to target in a test container regardless.
#
# Depends on: lib/menu.sh, lib/config.sh being sourced first.
