manage playground information

[mhenke]

User Story
As an administrator, I want to manage playground information to ensure it's up-to-date and accurate.

Acceptance Criteria
Given that I am an administrator responsible for managing playground information, when I update playground details, then the changes should be reflected in the app, and the information should remain accurate.

1. The platform should provide an interface for administrators to edit, update, and delete playground information.
2. After making changes, the updated information should be displayed or removed from the application.
3. Users accessing the platform should see the most recent, active, and accurate playground details.
4. Any changes made by administrators should be tracked and documented for reference.
