Changes

With this PR, we are introducing the bulk actions handled via background tasks.

By default, the users will be able to perform the following bulk actions:

• Publish entries
• Unpublish entries
• Move entries to a folder
• Move entries to the trash bin
• Restore entries from the trash bin
• Permanently delete entries

api-headless-cms-tasks

The package is responsible for:

• adding task definitions that create subtasks after listing entries selected for the provided bulk action
• adding task definitions responsible for processing the subtasks created after listing
• registering the CmsGraphQLSchemaPlugin allowing to trigger bulk actions via custom mutation

app-headless-cms + app-trash-bin

When all entries are selected, a new banner will prompt asking if the user wants to select all of them.

The banner will appear if:

• more entries are present but not yet loaded in the list (hasMoreItems: true)
• the current folder contains child folders - currently, we are not checking if child folders are empty

In case the user confirms the selection, the action will be performed by the designated background task instead of the default in-series client worker.

At the moment:

• In the case of selecting “all entries,” the selected count (e.g., 15 entries selected) will be replaced by a generic “All entries selected” as the application doesn't know the number of entries in sub-folders without additional queries.
• We are not providing real-time feedback on the background task status. The user needs to reload the page to see the status update.
