Calendar elements are now lowercase and wrapped in an object

[Copilot]

Pull Request Overview

This pull request updates calendar-related code to use lowercase property names and wraps calendar elements in a wrapper object for a more consistent API response. Key changes include:

• Renaming calendar element properties (e.g., ID → id, Name → name) in the model, service, controller, and YAML configuration.
• Introducing a new CalendarWrapper model to encapsulate calendar elements.
• Adjusting log messages and method calls in related services to reflect the new naming convention.
