Pull request overview

This PR updates GoogleTest fixture class names to be unique across unit and component test binaries, avoiding naming collisions (e.g., in unity/jumbo builds or when linking tests together).

Changes:

• Rename unit test fixtures from *Test to *UTest (and update corresponding TEST_F usages).
• Rename component test fixtures from *Test to *CTest (and update corresponding TEST_F usages).
• Apply the renaming consistently across multiple feature test suites (TextToSpeech, Metrics, Network, etc.).
