refactor: improve MCP client timeout handling and client tests

- Add separate initializationTimeout configuration parameter distinct from requestTimeout
- Change ping() method to return Void instead of Object for better API clarity
- Refactor tests to consistently use StepVerifier instead of mixing assertion styles
- Rename ServletSse* test classes to HttpSse* for better naming consistency
