This commit replaces the O(N) `find` and O(N*M) nested array iterations inside the `TripsPage` React component with a precomputed O(1) `Map` lookup for station names. This directly addresses re-render lags when a user has a large number of recorded trips. Co-authored-by: OsakaLOOP <68284076+OsakaLOOP@users.noreply.github.com>

💡 What: Added an O(1)
stationNameMapusinguseMemoinTripsPage.tsxand refactored the station name rendering logic for both regular and walk trips to use this map instead of iterating arrays.🎯 Why: Previously, on every render, the component would execute
Array.findover nested lists of lines and stations. This becomes a severe bottleneck as the user accumulates more trips and more customrailwayDatais imported.📊 Impact: Reduces component re-render time by transforming O(N*M) rendering lookups into O(1) lookups.
🔬 Measurement: Verified the types and rendering logic using
npx tsc --noEmitand manual logic review. No new dependencies were added.PR created automatically by Jules for task 7310510038377825847 started by @OsakaLOOP
