Polish Waybar and add Bluetooth and walker service

Refactor Waybar config and CSS: add rgb/radius helpers and tweak
sizes, spacing, colors, tooltips, icons and transitions

Enable gtk-layer-shell and reload-on-change. Move exec-once into
settings and adjust modules and workspaces formatting

Add blueman and bluez to basic apps for Bluetooth support

Add elephant to home packages and add a systemd user service for
walker; change Hyprland exec-once to enable and start elephant.service
