Module wallet_auth 

Authentication middleware for ChainStream API.

Supports three modes:

• API Key: X-API-KEY header (via ApiKeyAuthMiddleware)
• Wallet signature: X-Wallet-* headers for x402 (via WalletAuthMiddleware)
• Bearer token: Authorization: Bearer header (via BearerAuthMiddleware in tests)
