Summary by Sourcery

Enforce API key validation for Ryzenth client initialization with proper bearer authorization and clean up README by removing outdated FAQ and updating example credentials

Enhancements:

• Require a valid API key from parent attribute or RYZENTH_API_KEY environment variable before initializing the client
• Inject the API key as a Bearer token in the RyzenthApiClient authorization header and raise AuthenticationError on invalid or missing key

Documentation:

• Remove the outdated FAQ section about free trial
• Update the JavaScript example to use a placeholder for the required API key
