fix(kba): fix draft deletion bug and add collapsible AutoGenSettings

- Fix delete draft error: use response.items instead of response.drafts
- Make AutoGenSettings card collapsible with chevron icon
  - Starts collapsed to reduce visual dominance
  - Smooth slide-down animation when expanded
  - Status badge visible in collapsed header
  - Clickable header with keyboard support (Enter key)
