Enhance SQS sink logging for better troubleshooting

[Davidding4718]

Is your feature request related to a problem? Please describe.
When debugging SQS sink issues, there is insufficient logging to understand why messages are being dropped, sent to DLQ, or rejected.

Describe the solution you'd like
Add comprehensive debug and info level logging to the SQS sink, specifically in SqsSinkBatch.java and related classes:

1. Size limit violations : Log when messages are rejected due to exceeding configured size limits

2. DLQ routing : Log the specific reason why messages are sent to DLQ with error details

3. SQS API errors : Log detailed error information for failed SQS requests

Describe alternatives you've considered (Optional)
