Merge upstream/main into feature/catalonia-cctv-cameras

Keeps PR #595's Catalonia CCTV pack in sync with upstream's DelDOT
CCTV pack (#699) and the wind/weather doc updates from #617. The
sources.js conflict was a false positive from git's line-based diff
interleaving two structurally similar but independent loader
functions (loadCataloniaSourcesFromOpenData / loadDelDOTSourcesFromOpenData);
resolved by keeping both as complete, separate functions.

Full unit suite passes (4743/4743, 1 pre-existing Node-version skip).
