Use shared button components in queue overlay (#6793)

## Summary
- replace raw button elements in queue progress overlay UI with shared
IconButton/TextButton/IconTextButton components
- remove forced justify-start from IconTextButton base and add explicit
alignment where needed
- keep queue overlay actions consistent with button styling patterns

## Testing
- pnpm typecheck
- pnpm lint:fix
