Add owner for media only for User auth

[DenTray]

Description

What needs to be done?

Update the media creation logic so that the owner_id field is assigned the ID of the authenticated user (Auth::id()) only if the current authenticated user is of the same type as the class specified in the media.classes.user_model configuration. Modify the auth.providers configuration to use a non-User model to test this conditional behavior.

Expected Outcome

What is the expected result?

• When an authenticated user matches the media.classes.user_model type, the media item's owner_id is set to the authenticated user's ID.

• When the authenticated user is of a different type, owner_id is not set.

• Changing the auth.providers config to a non-User model properly triggers the conditional check.

• Media creation works correctly without errors in both cases.

Verification Scenarios

How can this be tested?

• Configure auth.providers to use the default User model and create media as that user; verify owner_id equals Auth::id().

• Change auth.providers to a different user model that differs from media.classes.user_model; create media and ensure owner_id is null or unset.

• Validate that no errors occur during media creation in either configuration.

• Ensure no debug information or errors appear in the console.
