Enable Record/Playback test mode for Sample tests

- Delete 13 @disabled test files (replaced by Sample tests)
- Modify Sample00-Sample16 to extend ContentUnderstandingClientTestBase
- Add testResourceNamer for reproducible random IDs in PLAYBACK mode
- Remove problematic sanitizers (AZSDK2003, AZSDK2030, AZSDK3423, AZSDK3430, AZSDK3493)
- Configure maven-surefire-plugin to include Sample*.java
- Use AZURE_CONTENT_UNDERSTANDING_ENDPOINT env var (matches .NET naming)
