Promote per-event structure and counter logs from info→warning

With total_rows=0 but all 200s, the parsing loop is silently discarding
all data. The structure log (books=, markets=, outcome_counts=) and
counter log (bookmakers=N outcomes=N skip_name=N etc.) were at info
level — invisible in HuggingFace Spaces. Now promoted to warning so
we can see exactly where rows are being dropped for each of 15 events.

Zero logic changes.
