fix: preserve chat input when processing queued messages

- Modified handleSendMessage to not clear input value when queueing
- Only clear selected images when queueing a message
- Input will be cleared when message is actually sent, not when queued
- Fixes #7861 where unsent text was lost when queued messages were processed
