Intervention model refactoring

* splits Intervention model into three main components
   * Intervention (main object)
   * LegalData (holds legal dates, laws, etc.)
   * ResponsibilityData (holds organizations and handler)
   * This way data can be extended more easily in the future
* refactors admin.py and usages in templates
* introduces UuidModel as a base class for BaseResource
