Enhanced Frontend Card Editing: Implementing Warning for Additional YAML Content

[Horstexplorer]

Currently, when users edit a card in YAML mode on a dashboard, they can add supplementary content like comments. However, attempting to save these changes leads to the loss of such data. This outcome can catch users off guard, as YAML specifications permit this addition, while it is dropped based due to how the frontend processes this data internally.

To enhance user experience and prevent data loss, it would be beneficial to implement a warning system. When users attempt to save content beyond what is being actually stored, a warning message should prompt them about the potential loss of additional data. This proactive measure would allow users to verify and back up data as necessary before proceeding with the storage process.
