feat: Add PublicBotsController for anonymous ShareCard access

- Created PublicBotsController with [AllowAnonymous] at class level
  to avoid policy authorization conflicts with the main BotsController
- Updated ShareCard.cshtml to use PublicBots controller for embed links
- Fixes HTTP 500 error when accessing ShareCard without authentication
