Pull Request Overview

This PR adds support for nested folder functionality in Azure Managed Grafana CLI commands. It allows creating subfolders within parent folders, improves folder search to handle nested structures, and updates folder listing and lookup logic to support hierarchical folder organization.

• Added parent_folder_uid parameter to folder creation for nested folder support
• Refactored folder listing to use a new search_folders utility function for better nested folder handling
• Updated folder lookup logic to search by UID first, then by title for improved folder identification
