Replaced Object.values.some() and Object.values.forEach() with early breaking for...in loops. This avoids array allocation on every call and allows us to exit early without full O(N) array traversals, lowering memory overhead and improving UI performance when iterating over large `railwayData` datasets.

💡 What: Replaced Object.values.some() and Object.values.forEach() with for...in loops that break early in AppLayout.tsx, RailRound.jsx, TripsPage.tsx and WalkTripEditor.tsx.
🎯 Why: Iterating over
Object.values()forces the runtime to allocate large intermediate arrays. Avoiding this via short-circuiting standardfor...inloops drastically cuts down memory allocations and redundant data traversals in critical data lookup routines across large objects likerailwayData.📊 Impact: Eliminates unnecessary O(N) memory allocations per call, turning full table scans into faster, short-circuit lookups during UI renders.
🔬 Measurement: Verify by executing the application and monitoring memory profiling when looking up station definitions or determining
needsCalc, which now run allocation-free and break upon success instead of exhausting the loop.PR created automatically by Jules for task 83638798854742047 started by @OsakaLOOP
