Memoized calculation logic and stabilized event handlers to reduce re-renders.


PR created automatically by Jules for task 2767940780448731141 started by @8faizahmed

💡 What:
- Memoized weight and balance calculations in `app/page.tsx` using `useMemo`.
- Wrapped `CalculatorView` in `React.memo` to prevent unnecessary re-renders.
- Stabilized inline event handlers in `app/page.tsx` using `useCallback`.

🎯 Why:
- The calculation logic was running on every render, even for unrelated state changes like UI toggles or dark mode switches.
- `CalculatorView` was re-rendering whenever `Home` re-rendered, even if its props hadn't changed, causing potential lag in the UI.

📊 Impact:
- Prevents recalculation of weight & balance when toggling "Show Info" or "Dark Mode".
- Prevents `CalculatorView` re-renders when interacting with unrelated parts of the app.
- Improved overall responsiveness.

🔬 Measurement:
- Verified that `CalculatorView` does not re-render when toggling UI flags.
- Confirmed `npm run build` passes with no type errors.
