Fix case_detail delete logic order bug

The delete handler was checking case notes first, then evidence,
but the display order is evidence first, then notes. This caused:
- Selecting evidence + pressing 'd' -> asked to delete a note
- Selecting note + pressing 'd' -> asked to delete evidence

Fixed by reordering the checks to match display order:
1. Check if index < len(evidence) -> delete evidence
2. Otherwise check if in notes range -> delete note

Now delete correctly targets the selected item type.
