Fix Inbox Management: EML link and add email detail screenshot

Corrections to Inbox Management documentation:

Table Columns:
- Fixed EML column description: "Download link" instead of "Checkmark (✓)"
- Clarified: "blank if not stored" for emails without stored .eml file

Email Detail Modal section:
- Added screenshot (approve-job.png) showing the email detail modal
- Screenshot displays: metadata section, email body, and approval interface
- Figure caption explains all visible components
- Screenshot reused from earlier documentation (already created)

These corrections accurately reflect the actual UI behavior.
