refactor: remove unused code and simplify installer

* Remove unused json import
* Remove unused settings registry update methods (_update_settings_registry, _remove_from_settings_registry)
  * the components themselves are responsible for registering in metadata/settings file
* Remove uninstall_component method
  * the components themselves are resonsible for their uninstall logic
* Simplify post-install validation logic
