fix: adjust Zeitwerk lazy loading in production

  -  Centralized constants make it easy to add dropdowns in the frontend
  -  Display name mappings available (e.g., Constants::Organization::TIER_NAMES)
  -  No more manual text entry - can use select inputs with predefined options
  -  Consistent validation across the application
  - Easier to maintain and update
