webui: Prevent sending messages while uploads are in progress

This fixes an issue where users could press Enter immediately after pasting an image,
which would submit the message with just the '[Uploading image.png...]' placeholder text.

Now the system:
1. Tracks uploads in progress
2. Prevents message submission while uploads are active
3. Shows visual feedback to the user
4. Disables the send button during uploads
