fix: resolve CI test failures and OOM kill in satellite tests

- pyproject.toml: sync missing deps (flask-wtf, flask-compress,
  simple-websocket, gunicorn, gevent, psutil, cryptography, meshcore,
  pre-commit) so test_requirements integrity check passes
- tests/conftest.py: set INTERCEPT_DISABLE_AUTH=1 so auth routes
  return 200 instead of 302 in tests
- routes/bluetooth_v2.py: add device_to_dict() helper that flattens
  heuristics to top level for test_bluetooth_api serialization tests
- utils/bluetooth/heuristics.py: evaluate() now returns the device so
  callers can chain; was returning None
- tests/test_satellite.py: reduce hours 48→2 in pass-prediction test
  to prevent OOM kill on GitHub Actions 7GB runner at the 59% mark
