test: Refactor WebSocket and speech tests for improved mocking and reliability

- Update WebSocket client test suite with more robust mocking
- Enhance SpeechToText test coverage with improved event simulation
- Simplify test setup and reduce complexity of mock implementations
- Remove unnecessary test audio files and cleanup test directories
- Improve error handling and event verification in test scenarios
