refactor: switch to home-manager module

Browse Source 
Systant is a userspace controller, so it makes sense to manage it
via home-manager rather than as a system service. This allows:
- Declarative per-user configuration
- Access to user's environment, PATH, and session
- Proper handling of audio, display, and other user resources

Usage in home-manager config:
  imports = [ inputs.systant.homeManagerModules.default ];
  services.systant.enable = true;
  services.systant.settings = { ... };
