notifications-tray-icon: add dedicated module and update flake input

Add notifications-tray-icon.nix module with overlay and home-manager
service config. Update flake input to colonelpanic8 fork and remove
stale HLS input follows. Clean up xmonad.nix by removing the old
overlay reference and commented-out service definition.
