Pro 4257 modal property

[falkodev]

Summary

https://linear.app/apostrophecms/issue/PRO-4257/as-a-developer-i-can-use-the-modal-property-in-my-batch-operations

• Use the modal property in batch operations
• Lay the groundwork for next ticket, where the modal should be the same (and the passed props too) between batch operations custom modal and doc context menu custom modal

What are the specific steps to test this change?

• Go to a module with export enabled
• Select multiple items and click "Export" in the batch operations menu
• Close the modal, click on the context menu of one item and click "Export"

The modal should be the same. It will be completed in another ticket.

PRO-4257 As a developer, I can use the modal property in my batch operations

Like for the method addContextOperation available in the module apostrophecms/doc, the batch operations must support the method modal, ex:

  batchOperations (self) {
    return {
      add: {
        export: {
          label: 'Download',
          modal: 'AposMyComponent'
        }
      }
    };
  }

This way, when clicking on the batch operation button, will be able to open a specific modal for more specific and complex behaviors.

We'll need this feature to be able to open the same export modal when clicking on the download button in batch operations than when clicking on the download button in the contextual menu of a single document.

You can base your work on the way it works currently for the addContextOperation method.

Acceptance Criteria

• The new property modal is available in each batch operation action.
• Whatever modal is opened when using this feature, it must at least get an array of IDs of the selected documents (to be able to perform needed API calls itself).

criteria is not a good name for this. operation would be good.
