fix: prevent queue from interfering with manual approval workflow

- Queue processing now pauses when approval buttons are showing (enableButtons is true)
- Messages typed during approval requests are queued instead of being sent immediately
- This prevents the unintended auto-rejection behavior when using QUEUE with manual approval

Fixes #6996
