🧪 feat: Claude Sonnet 4 - 1M Context Window (Beta Header) (#9093)

Browse source 
* adding beta header context-1m-2025-08-07 to claude sonnet 4 to increase contact window to 1M tokens

* adding context-1m beta header to test cases

* ci: Update Anthropic `getLLMConfig` tests and headers for model variations

- Refactored test cases to ensure proper handling of model variations for 'claude-sonnet-4'.
- Cleaned up unused mock implementations in tests for better clarity and performance.

* refactor: regex in header retrieval for 'claude-sonnet-4' models

* refactor: default tokens for 'claude-sonnet-4' to `1,000,000`

* refactor: add token value retrieval and pattern matching to model tests
