Do not create a config file from HM if settings is not set

[aster-void]

Is your feature request related to a problem? Please describe.
I like to manage my config files myself using stow, rather than letting home manager do it.
the home manager module seems to always generate the config, no matter the configuration.

this is my HM config:

{
  programs.hyprpanel = {
    enable = true;
    overlay.enable = true;
    hyprland.enable = true;
  };
}

Describe the solution you'd like
I'd like the config to be linked only when there's at least one config.

Describe alternatives you've considered
idk, like use HM to config hyprpanel?

Additional context

it may look like this:

home.files.(path).text = lib.mkIf (cfg.settings != {}) ''
  # how it's currently done...
'';

search the home-manager repo for references. for example, tmate, jujutsu, rbenv, lazygit, and awscli do it like this, to name a few.

settings will never be an empty set because of the defaults and how the HyprPanel config doesn't use JSON objects yet (waiting for #497) but I will add another option to disable the config generation. Will be enabled by default cuz it seems the majority use it.

If merged, set config.enable = false
