Fix quick command executions not appearing in execution tab

Changes:
- Create execution record in database when quick command is sent
- Store initial log entry with command details
- Broadcast execution_started event to update UI
- Display quick commands as "[Quick Command]" in execution list
- Fix worker communication to properly track all executions
