Stop logging faucet request secrets

[afurm]

Summary

• Removes logging of raw request headers from /api/request.
• Stops logging the bearer bypass token value.
• Keeps a minimal non-secret request log that records the client IP and whether an auth bypass token was present.

Why

The faucet request handler previously logged the full headers() object and the raw Authorization bearer token used for bypass checks. In production, that could expose session cookies, authorization headers, or privileged bypass tokens through application logs.

Validation

• npm run lint
• npm run build

Both passed. The repo still reports an existing React hook dependency warning in components/AirdropForm.tsx, unrelated to this change.

@afurm is attempting to deploy a commit to the Solana Foundation Team on Vercel.

A member of the Team first needs to authorize it.
