🔒 Fix SSRF vulnerability in RestClient host configuration

[rustyy]

🎯 What: Validates the opts.host configuration provided to the RestClient using the built-in URL class.

⚠️ Risk: The previous "${string}" union type allowed for any arbitrary string to be passed into the API calls, potentially allowing a malicious user/configuration to cause an SSRF (Server-Side Request Forgery) by interacting with unintended internal resources or external sites through the SDK's host argument.

🛡️ Solution: The change introduces a try/catch block that parses the host through new URL(opts.host). It will now throw an Error and block the execution if the given host does not evaluate to a valid URL structure. Tests were also added ensuring correct functionality.
