auto-claude: subtask-2-1 - Remove showFiles auto-expand on draft restore

Since the Referenced Files section is now always visible, remove the
conditional setShowFiles(true) in the useEffect that loads drafts.

Changes:
- Remove unused showFiles state variable
- Remove conditional that auto-expanded files section when restoring drafts
- Remove auto-expand call in handleDragEnd (section is always visible)
- Remove showFiles reset in resetForm
