Fix: Move Historical Attack Analysis to Threat Analysis menu

Issue: Historical Attack Analysis was in its own "System Diagnostics"
category with only one tool, but it's actually threat analysis.

Changes:
- Added Historical Attack Analysis to Threat Analysis menu (option 6)
- Removed System Diagnostics sub-menu entirely (both functions)
- Updated main security menu from 5 to 4 categories
- Removed option 5 and its handler

New Structure:
Main Security Menu (4 categories):
  1) Threat Analysis (6 tools) ← Historical Attack Analysis moved here
  2) Live Monitoring (4 tools)
  3) Log Viewers (4 tools)
  4) Security Actions (3 tools)

Benefits:
- More logical grouping - analyzing attacks is threat analysis
- No orphan category with only one tool
- Cleaner main menu (4 options vs 5)

Code Changes:
- Added: +2 lines (option 6 in show/handle)
- Removed: -30 lines (System Diagnostics menu)
- Net: -28 lines
