feat: Replace image-only attachment with general file attachment support

- Add comprehensive file processing system with MIME type detection
- Support multiple file categories (images, documents, code, data, archives, config)
- Implement 10MB file size limit and intelligent text/binary handling
- Replace camera icon with paperclip icon in chat interface
- Add selectFiles message types and handlers
- Update translations for attachFiles across all languages
- Maintain backward compatibility with existing image functionality

Resolves #5532
