[feat] Add bulk import failure info API endpoint (#2035)

* [feat] Add bulk import failure info API endpoint

- Add import_fail_info_bulk endpoint to both glob and legacy manager servers
- Supports bulk processing of cnr_ids and urls arrays in single request
- Maintains same error handling pattern as original import_fail_info API
- Reduces API calls from N to 1 for conflict detection optimization
- Validates input parameters and provides proper error responses

* modified: remove manager button completely. Now, even when using the legacy UI, it must always be accessed through the menu.

* chore(api): Add temporary cache reload for import_fail_info_bulk
