feat: enhance message sending with image-only mode and batch operations

- Added sendImageOnly toggle to allow sending images without text content
- Implemented validation logic to ensure either content or images are present before sending
- Added openMessageModalWithFiles method to send stage-specific files to group chat
- Added sendSpaceAllImages method to send all images from a space's delivery stages
- Enhanced sendMessage to properly handle image and text message creation via deliveryMessageService
- Auto
