[Repo Assist] fix(web): remove debug console.log and add FeatureFlagsModal error state

[github-actions]

🤖 This PR was created by Repo Assist, an automated AI assistant.

Summary

Two small but clear improvements to the React frontend:

1. Remove debug console.log statements (Task 5 — Coding Improvements)

Three console.log calls were left in production code:

File	Line	Statement
CarCard.tsx	~13	console.log(\Toggling ownership for car ${car.year}`)`
Home.tsx	~56	console.log(\Loaded ${winnersData.length} winners`)`
Home.tsx	~75	console.log(\Updated ownership for ${updatedCar.year} ${updatedCar.model}`)`

These log to the browser console on every user interaction and successful API response — noisy and unhelpful in production. All three are removed. The existing console.error calls for genuine error cases are kept.

2. Add error state to FeatureFlagsModal (Task 3 — Bug Fix)

Before: When the /flags/{userId} API call failed (network error or non-OK response), the catch block only logged to the console and set loading: false. Because flags remained an empty object, the modal showed "No flags available" — misleading users into thinking there are no flags, rather than that a load error occurred.

After: A fetchError state is added. On failure the modal shows "Failed to load flags. Please try again." The error resets to null at the start of each fetchFlags call, so retrying (e.g., re-opening the modal) shows fresh state. The .error CSS class is already defined globally in index.css.

Subject: [PATCH] fix(web): remove debug console.log and add FeatureFlagsModal
 error state

- CarCard: remove debug console.log in toggleOwnership handler
- Home: remove debug console.log on winners load success and ownership update
- FeatureFlagsModal: add fetchError state so users see an error message
  instead of misleading 'No flags available' when the flags API call fails
