Class BasicAuthMethod

HTTP Basic Authentication or form-based login.

Strategy determines HOW the credentials are applied:

• 'HttpHeader': Sets the HTTP Authorization header with Base64-encoded credentials on all requests to matching domains. Works for HTTP Basic Auth challenges.
• 'FormLogin': Does NOT set any headers. Instead, the engine injects the credentials into the Controller LLM's context so it can navigate the login form, type the username/password, and submit. Useful for testing web UIs with form-based auth.
