Added URL Argument to Call method

[FeezyHendrix]

Problem: The current call method is limited to using a fixed base URL. It does not support sending requests to a different hostname or port, which restricts its flexibility in multi-environment or distributed system setups.

Solution: This update introduces the url key as an optional parameter in the call method. When provided, the process constructs the request URL using the specified hostname and port. If the URL key is omitted, the method defaults to the existing base URL.

Usage Example:

call('example.method', {
  url: 'http://localhost:3001'
});

This resolves the request to:

http://localhost:3001/api/method/example.method
