Add plugin version management and UI enhancements

Introduced enable/disable functionality for plugin versions, including new methods in `MediatorExtensions`, handlers, and API endpoints. Updated `PluginDetails` to display active status and added UI controls for owners to toggle visibility.

Enhanced the UI with improved navigation, footer, and button styles. Added new pages for Privacy Policy, Terms of Service, and Contact information. Updated `app.css` with a new primary color and styling improvements.

Implemented `AuthorizationMessageHandler` for secure cookie handling in HTTP requests. Extended `IApiClient` with a `PutAsync` method and updated `StatsApiService` for plugin version management.

Replaced the hero banner image and performed minor refactoring for code consistency.
