feat: view config feature flag (#13171)

* feat: add view_configurations feature flag

  - Add feature flag provider and hooks to admin dashboard
  - Add backend API endpoint for feature flags
  - Create view_configurations feature flag (disabled by default)
  - Update order list table to use legacy version when flag is disabled
  - Can be enabled with MEDUSA_FF_VIEW_CONFIGURATIONS=true env var

* fix: naming

* fix: feature flags unauthenticated

* fix: add test
