SEO: broaden curated weather events beyond the US/Anglosphere (#101)

Common-sense coverage pass on city_events.py: the list was 10/31 US and heavily
Anglosphere with no Latin America, no Middle East, and only London/Paris for all of
continental Europe. Add 9 verified events filling those gaps — Los Angeles (2025
wildfires), Moscow (2010 heat/wildfires), Madrid (2021 Storm Filomena), Athens (2018
Attica fires), Seoul (2022 floods), Dubai (2024 floods), Jeddah (2009 floods), Sao
Paulo (2014-17 drought), Rio de Janeiro (2010 floods). Every Wikipedia link
verified to resolve. 40 events total; nothing removed (no factual errors found).
