[Reporting] Reorganize UI components

[tsullivan]

Summary

Needed for: #102833

In the previous code, it was difficult to understand the purpose of many of the React components under Reporting. There was a single components folder with files that are used in different places in the UI.

This PR organizes the components based on purpose and where they are in the UI:

• management: components for the Management UI
• notifier: components for the job status toast messages
• panel_actions: Dashboard panel Share menu items for Reporting
• share_menu: Dashboard panel Share menu items for Reporting
