Fix category display and tool counts in web UI

- Categories API now includes dynamic categories from database
  (categories used by tools but not in predefined list)
- Add total_tools to categories API meta for accurate All Tools count
- Fix web routes to use total_tools instead of summing category counts
- Dynamic categories get auto-generated descriptions

This fixes:
- "All Tools" showing 2 instead of 4
- Categories like "code-analysis" and "education" not appearing
- Incorrect category counts in sidebar
