The automatic cast feature was failing because the Neynar SDK returns an array of users for an ETH address, but the code was expecting a single object. I fixed the indexing in both app/api/neynar/route.ts and app/api/post-join-cast/route.ts.

Additionally, I standardized the referral links to use the Farcaster Universal Link format (https://farcaster.xyz/miniapps/...) and implemented a robust fallback mechanism in the frontend. If the server-side cast fails (e.g., due to missing environment variables), the manual 'Share on Farcaster' button will now correctly appear, ensuring users can still share their actions.

I verified the changes by running a full build, executing the smart contract test suite, and performing visual verification with Playwright.

- Fixed Neynar user lookup logic in API routes to correctly handle the array response from the SDK.
- Standardized referral links to use the Farcaster Universal Link format for better deep-linking.
- Enhanced frontend with fallbacks to manual sharing if automatic casting fails.
- Improved error logging in both frontend and backend for debugging Neynar interactions.
