Wire the web-scraper as a third update fallback, add regression tests

AutoUpdateAndLearn.update_data() now falls back to LottoWebUpdater
(lotto.de scraping) when the API chain (Lottoland/GitHub/lottoAPI)
returns no new data, matching the pattern already in production on
the Eurojackpot sibling project. Required installing beautifulsoup4
into the venv - its absence would have crashed the entire update
script the moment the fallback import was added, not just the
fallback path itself, so this needed verifying before wiring it in.

Also adds tests/test_popularity_score.py (pytest): regression coverage
for the popularity/EV score against known overplayed combinations
(1-2-3-4-5-6, 5-10-15-20-25-30) and the Superzahl EV ordering. Verified
against the pre-fix code (commit 8c2089d) that these tests would
actually have caught the sum-extremity bug fixed in e05f1f1 - this
had previously only been caught by manual spot-checking.
