Asset UI does not display extra metadata in Assets views #57566

Apache Airflow version

3.1.1

If "Other Airflow 2/3 version" selected, which one?

What happened?

When viewing Assets in the Airflow 3.1.1 UI, the context-specific metadata attached to assets is not shown anywhere in the UI. For example, if an asset is defined with extra={...} (see below), this information is not visible in the asset event details, asset event list, or any related asset views. This makes it difficult for users to see or audit static asset metadata during asset event inspection. Only AssetEvent extra is displayed.

Asset(
    's3://bucket/mydata.csv',
    extra={'owner': 'Sir Airflow'},
)

What you think should happen instead?

The UI should display the extra dictionary (static asset metadata) somewhere in the Assets view, ideally together with other asset details. This could be shown as a dedicated section, or grouped with asset information in the event card or detail modal. Showing this field would allow users to see static asset metadata alongside event-specific metadata (extra).

How to reproduce

1. Create an asset with extra={...}.
2. Emit one or more asset events for the asset.
3. Open the Assets view in the Airflow UI.
4. Observe that the static asset metadata (extra) is not displayed anywhere.
