# Version      : 1.2
# ==========================================================
# Description:
# ProxMenux configuration / settings menu. Options are shown
# conditionally based on the install type and current state:
#
#   - ProxMenux Monitor (Activate / Deactivate + Show Status)
#       Only if proxmenux-monitor.service is registered with
#       systemd. Toggles between active / inactive states.
#
#   - Change Release Channel
#       Switches between Stable (main branch) and Beta (develop
#       branch) by running the official installer for each channel.
#
#   - Change Language
#       Only on the Translation install type (venv +
#       config.json.language present). Languages: en / es / fr /
#       de / it / pt.
#
#   - Show Version Information
#       Always shown. Reports installed components, files,
#       virtual environment state and current language.
#
#   - Uninstall ProxMenux
#       Always shown. Interactive uninstall with optional
#       dependency removal (jq, dialog, python3-*, ...) and
#       restoration of /root/.bashrc + /etc/motd backups.
