* ChannelsTable
- Added row-level checkboxes to the model-testing table for multi-selection
- Implemented cross-page “Select All / Deselect All” via rowSelection.onSelectAll
- Introduced allSelectingRef to ignore redundant onChange after onSelectAll
- Added “Copy Selected” button to copy chosen model names (comma-separated) using helpers.copy
- Added “Select Successful” button to auto-tick all models that passed testing
- Moved search bar and new action buttons into the modal title for better UX
- Centralised page size constant MODEL_TABLE_PAGE_SIZE in channel.constants.js
- Fixed pagination slicing and auto-page-switch logic during batch testing
