feat: add bulk delete functionality for features

- Introduced a new endpoint `/bulk-delete` to allow deletion of multiple features at once.
- Implemented `createBulkDeleteHandler` to process bulk delete requests and handle success/failure responses.
- Updated the UI to include a bulk delete option in the BoardView component, with confirmation dialog for user actions.
- Enhanced the HTTP API client to support bulk delete requests.
- Improved the selection action bar to trigger bulk delete functionality and provide user feedback.
