Temporarily disable Django instrumentation to test Host header issue

- Comment out DjangoInstrumentor().instrument() to test if it's causing duplicate Host headers
- Remove unused DjangoInstrumentor import
- Keep other instrumentation (database, HTTP client) enabled
- This is a temporary test to isolate the Host header duplication issue
