Consolidates bar-settings into a single 'settings' plugin with sidebar
categories: Defaults, Style, Bar, System, Plugins. Updates supporting
commands (omarchy-launch-settings, omarchy-style-corners-quickshell,
omarchy-theme-list-with-previews, omarchy-hyprland-monitor-scaling-set)
and refreshes sidebar glyphs to Nerd Font icons.
The legacy 'workspaces' built-in renders cleaner than the animated
workspacesPro file widget. Removed the widget file, its first-party
registration in Bar.qml, and updated the default layouts and docs.
'workspaces' loses the (legacy) tag in the catalog since there's no
alternative anymore.
