Test SDK resilience to callback implementation errors

[sirknightj]

Issue #, if available:

• N/A

What was changed?

• Added integration tests: StreamCallbacksErrorHandlingIntegTest to validate SDK error handling when user-implemented stream callbacks throw exceptions and errors

Why was it changed?

• To ensure the Kinesis Video Streams Producer SDK gracefully handles application errors in user callback implementations without breaking the streaming pipeline.
• This addresses a critical reliability requirement where SDK robustness should not depend on perfect user code.

How was it changed?

• Created fault-injection integration test that intentionally throws RuntimeException in fragmentAckReceived callback. Streams to a Kinesis Video Stream using the ImageFileMediaSource similar to DemoAppMain.
• Test verifies SDK continues normal operation and receives PERSISTED fragment acknowledgments despite callback errors

What testing was done for the changes?

• Ran the tests locally
• Ran DemoAppMain locally
