fix(e2e): add decision routes for all 14 LoRA categories in test profiles

The production-stack and llm-d E2E test profiles were failing with
0-1% domain classification accuracy because they only configured
decision routes for 1-2 categories while using LoRA intent classifiers
that classify into 14 categories.

When the classifier correctly identified categories like "biology",
"health", or "math", no matching decision existed, causing
"decision evaluation failed: no decision matched" errors.

Changes:
- production-stack: Added decision routes for all 14 categories
  (business, philosophy, biology, health, computer science,
  engineering, psychology, math, chemistry, physics, history,
  law, economics, other)
- llm-d: Added decision routes for all 14 categories with
  intelligent grouping (sciences, social sciences, humanities)

Results:
- production-stack domain classification: 1% → 53% accuracy (50x improvement)
- All 12 production-stack E2E tests now pass

This fix ensures LoRA auto-detection works properly by providing
decision routes for all categories that the classifier can identify.
