Request for In-App Editing of Chart Metadata (Alias, Artist, Name)

**Description**:
I would like to request a feature in AstroDX that allows users to edit beatmap metadata, including alias, artist, and title, directly within the application. This would greatly improve user experience by enabling edits without needing to leave the app.

**Motivation**:
Currently, users have to manually edit files to modify these pieces of information, which is a cumbersome and error-prone process. By providing an in-app editing feature, the workflow would be simplified, and mistakes could be minimized.

**Expected Outcome**:
- Users will be able to directly modify the alias, artist, and title of beatmaps within the application.
- A simple and user-friendly interface will be provided to facilitate these edits.

The issue describes adding in-app editing for beatmap metadata (alias, artist, title). First, locate where beatmap metadata is currently loaded and saved (likely in a model or data service). Then, examine the existing UI to find where to add an edit interface. 'Done' means the user can modify these fields in the app and changes persist.
