Fix module-level transformers import crashing manage.py test

[Copilot]

• Identify root cause: from transformers import pipeline at module level in core/views.py causes import failure when transformers is not installed, crashing manage.py test
• Fix: moved the transformers import inside the analyze_sentiment function where it's actually used (lazy import)
• Identify CI failure: requests module was missing from requirements.txt, causing ModuleNotFoundError: No module named 'requests' in CI after the transformers fix
• Fix: added requests to requirements.txt
• Verified python manage.py test runs successfully (exits cleanly with "Found 0 test(s). Ran 0 tests in 0.000s")

The CI was still failing because requests was missing from requirements.txt. After the transformers fix, Django could load URL configs but then crashed on import requests (used throughout views.py for weather/pollen/IP APIs). Fixed in d11f85f by adding requests to requirements.txt.
