web client: Can delete copy that is not in ideal status without warning

Evergreen version: master

In certain web client interfaces, a user with COPY_DELETE_WARNING.override can delete a copy whose status has restrict_copy_delete set to true without any warning. If the user does not have permission to override this warning, they get a message that doesn't clearly indicate what is preventing the deletion.

For users that have the aforementioned permission, if they attempt to delete an item with a checked out status, for example, from the item status interface or the holdings view interface, the item will delete without a warning prompt. In the xul client, this user would get a prompt that says 'the copy in question is not in an ideal status for deleting.' The user then needs to force the action to proceed.

This prompt does appear in the web client copy bucket interface.

For users that do not have the aforementioned permission, the prompt they receive says 'Permission Denied: COPY_DELETE_WARNING.override. Another staff member with the above permission may authorize this specific action. Please notify your library administrator if you need this permission. If you feel you have received this exception in error, please inform your friendly Evergreen developers or helpdesk staff of the above permission.'

This message doesn't clearly convey why the copy cannot be deleted, leading to a situation where an administrator may decide to override the message without realizing they are deleting an item that is in precarious status.

The web client copy buckets interface has a clear warning prompt for users who do and do not have the permission to override this block. This prompt should be employed in the item status and holdings view interfaces as well as any other interfaces where copies can be deleted.
